Feedback 1: The README really needs more details. What does it do/not do? Don't assume people have used Cursor. If it is a Cursor alternative, does it support all of Cursor's features?
As a non-Cursor user who does AI programming, there is nothing there to make me want to try it out.
Feedback 2: I feel any new agentic AI tool for programming should have a comparison against Aider[1] which for me is the tool to benchmark against. Can you give a compelling reason to use this over Aider? Don't just say "VSCode" - I'm sure there are extensions for VSCode that work with Aider.
As an example of the questions I have:
- Does it have something like Aider's repomap (or better)?
Thanks for the feedback. We'll definitely add a feature list. To answer your question, yes - we support Cursor's features (quick edits, agent mode, chat, inline edits, links to files/folders, fast apply, etc) using open source and openly-available models (for example, we haven't trained our own autocomplete model, but you can bring any autocomplete model or "FIM" model).
We don't have a repomap or codebase summary - right now we're relying on .voidrules and Gather/Agent mode to look around to implement large edits, and we find that works decently well, although we might add something like an auto-summary or Aider's repomap before exiting Beta.
Regarding context - you can customize the context window and reserved amount of token space for each model. You can also use "@ to mention" to include entire files and folders, limited to the context window length. (you can also customize the model's reasoning ability, think tags to parse, tool use format (gemini/openai/anthropic), FIM support, etc).

An important Cursor feature that no one else seems to have implemented yet is documentation indexing. You give it a base URL and it crawls and generates embeddings for API documentation, guides, tutorials, specifications, RFCs, etc in a very language agnostic way. That plus an agent tool to do fuzzy or full text search on those same docs would also be nice. Referring to those @docs in the context works really well to ground the LLMs and eliminate API hallucinations
Back in 2023 one of the cursor devs mentioned [1] that they first convert the HTML to markdown then do n-gram deduplication to remove nav, headers, and footers. The state of the art for chunking has probably gotten a lot better though.
This is a good point.We've stayed away from documentation assuming that it's more of a browser agent task, and I agree with other commenters that this would make a good MCP integration.
I wonder if the next round of models trained on tool-use will be good at looking at documentation. That might solve the problem completely, although OSS and offline models will need another solution. We're definitely open to trying things out here, and will likely add a browser-using docs scraper before exiting Beta.
RobinL · 2h ago
I agree that on the face of it this is extremely useful. I tried using it for multiple libraries and it was a complete failure though, it failed to crawl fairly standard mkdocs and sphynx sites. I guess it's better for the 'built in' ones that they've pre-indexed

Am I the only one that has had bad experiences with aider? For me each time I've tried it, I had to wrestle with and beg the AI to do what I wanted it to do, almost always ending in me just taking over and doing it myself.
If nearly everytime I use it to accomplish something it gets it 40-85% correct and I have to go in to fix the other 60-15%, what is the point? It's as slow as hand writing code then, if not slower, and my flow with Continue is simply better:
1. CTRL L block of code
2. Ask a question or give a task
3. I read what it says and then apply the change myself by CTRL C and then tweaking the one or two little things it inevitably misunderstood about my system and its requirements
CuriouslyC · 1h ago
Aider is quite configurable, you need to look at the leaderboard and copy one of the high performing model/config setups. Additionally, you need to autoload files such as the readme and coding guidelines for your project.
Aider's killer features are integration of automated lint/typecheck/test and fix loops with git checkpointing. If you're not setting up these features you aren't getting the full value proposition from it.

This is exactly the issue I have with copilot in office. It doesn't learn from my style so I have to be very specific how I want things. At that point it's quicker to just write it myself.

Llm performance is 100% dependent on the model you're using so you ca hardly generalize from a small model you run locally on a cpu.

andrewpareles · 5h ago
Void dev here! The biggest players in AI code today are full IDEs, not just extensions, and we think that's because they simply feel better to use by having more control over the UX.
There are certainly a lot of alternatives that are plugins(!), but our differentiation right now is being a full open source IDE and having all the features you get out of the big players (quick edits, agent mode, autocomplete, checkpoints).
Surprisingly, all of the big IDEs today (Cursor/Windsurf/Copilot) send your messages through their backend whenever you send a message, and there is no open source full IDE alternative (besides Void). Your connection to providers is direct with Void, and it's a lot easier to spin up your own models/providers and host locally or use whatever provider you want.
We're planning on building Git branching for agents in the next iteration when LLMs are more independent, and controlling the full IDE experience for that will be really important. I worry plugins will struggle.

Claude Code (neither IDE nor extension) is rapidly gaining ground, it's biggest current limitation being cost, which is likely to get resolved sooner rather than later (Gemini Code anyone?).

Just want to share our thinking on terminal-based tools!
We think in 1-2 years people will write code at a systems level, not a function level, and it's not clear to us that you can do that with text. Text-based tools like Claude Code work in our text-based-code systems today, but I think describing algorithms to a computer in the future might involve more diagrams, and terminal will not be ideal. That's our reasoning against building a tool in the terminal, but it clearly works well today, and is the simplest way for the labs to train/run terminal tool-use agents.

The versioning and git branching sounds really neat, I think! Can you say more about that? Curious if you've looked at/are considering using Jujutsu/JJ[0] in addition or instead of git for this, I've played with it some, but been considering trying it more with new AI coding stuff, it feels like it could be a more natural fit than actually creating explicit commits for every change, while still tracking them all? Just a thought!
Interesting, thanks for sharing! We planned on spinning up a new Git branch and shallow Git clone (or possibly worktree/something more optimized) for each agent, and also adding a small auto-merge-with-LLM flow, although something more granular like this might feel better. If we don't use a versioning tool like JJ at first (may just use Git for simplicity at first), we will certainly consider it later on, or might end up building our own.

If you're open to something CLI-based, my project Plandex[1] offers git-based branching (and granular versioning) for AI coding. It also has a sandbox (also built on git) that keeps cumulative changes separate from project files until they're ready to apply.
Isn't continue.dev also open source and not using 'their backend' when sending stuff? I didn't use it in a while, but I know it had support for llama, local models for tab completions, etc.

Yep, Void is a VSCode fork, but we're definitely not wed to VSCode! Building our own IDE/browser-port is not out of the picture. We'll have to see where the next iteration of tool-use agents takes us, but we strongly feel writing typescript/rust/react is not the endgame when describing algorithms to a computer, and a text-based editor might not be ideal in 10 years, or even 2.

Chances are definitely not 0 that we end up moving away from VSCode as things progress.
aylmao · 46m ago
> It feels like everyone and their mother is building coding agents these days.
For real. I think it's because code editors seem to be in that perfect intersection of:
- A tool for programmers. Programmers like building for programmers.
- A tool for productivity. Companies will pay for productivity.
- A tool that's clearly AI-able. VC's will invest in AI tools.
- A tool with plenty of open source lift. The clear, common (and extreme?) example of this being forking VSCode.
Add to that the recent purchase of VSCode-fork [1] Windsurf for $3 billion [2] and I suspect we will see many more of these.
My 2c: I rarely need agent mode. As an older engineer, I usually know what exactly needs to be done and have no problem describing to the LLM what to do to solve what I'm aiming to do. Agent mode seems its more for novice developers who are unsure what tasks need to be broken down and the strategy that they are then solved.

Agent mode seems to be better at realizing all the places in the code base that need to be updated, particularly if the feature touches 5+ files, whereas editor starts to struggle with features that touch 2-3 files. "every 60 ticks, predict which items should get cached based on user direction of travel, then fetch, transform and cache them. when new items need to be drawn, check the cache first and draw from there, otherwise fetch and transform on demand." this touches the core engine, user movement, file operations, graphics etc and agent mode seems to have no problem with this at all.

Same here. It’s fine for me to use the ChatGPT web interface and switch between it and my IDE/editor.
Context switching is not the bottleneck.

CuriouslyC · 1h ago
Sorry to say but this workflow just isn't great unless you're working on something where AI models aren't that helpful -- obscure language/libraries/etc where they hallucinate or write non-idiomatic solutions if left to run much by themselves. In that case, you want the strong human review loop that comes from crafting the context via copy paste and inspecting the results before copying back.
For well trodden paths that AI is good at, you're wasting a ton of time copying context and lint/typechecking/test results and copying back edits. You could probably double your productivity by having an agentic coding workflow in the background doing stuff that's easy while you manually focus on harder problems, or just managing two agents that are working on easy code.

I couldn't use AI code without agentic mode.
At it's most basic, agentic mode is necessary for building the proper context. While I might know the solution at the high level, I need the agent to explore the code base to find things I reference and bring them into context before writing code.
Agentic mode is also super helpful for getting LLMs from "99%" correct code to "100%" correct code. I'll ask them to do something to verify their work. This is often when the agent realizes it hallucinated a method name or used a directionally correct, but wrong column name.

"Novice mode" has always been true for the newcomer. When I was new, I really was at the mercy of:
1) Authority (whatever a prominent evangelist developer was peddling)
2) The book I was following as a guide
3) The tutorial I was following as a guide
4) The consensus of the crowd at the time
5) Whatever worked (SO, brute force, whatever library, whatever magic)
It took a long ass time before I got to throw all five of those things out (throw the map away). At the moment, #5 on that list is AI (whatever works). It's a Rite of Passage, and because so much of being a developer involves autodidacticism, this is a valley you must go through. Even so, it's pretty cool when you make it out of that valley (you can do whatever you want without any anxiety about is this the right path?). You are never fearful or lost in the valley(s) for the most part afterward.
boredtofears · 5h ago
If you use AI agents for all your work as a novice do you ever make it out of the valley?
ivape · 5h ago
Yeah.
Most people have not deployed enough critical code that was mostly written with AI. It's when that stuff breaks, and they have to debug it with AI, that's when they'll have to contend with the blood, sweat, and tears. That's when the person will swear that they'll never use AI again. The thing is, we can never not use AI ever again. So, this is the trial by fire where many will figure out the depth of the valley and emerge from it with all the lessons. I can only speculate, but I suspect the lessons will be something along the lines of "some things should use less AI than others".
I think it's a cool journey, best of luck to the AI-first crowd, you will learn lessons the rest of us are not brave enough to embark on. I already have a basket of lessons, so I travel differently through the valley (hint: My ship still has a helm).

You'll throw away the mess, and let a newer LLM build a better version in a couple of days. You ask the LLM to write down the specs for the newer version based on the old code.

It's in poor taste to bring up this example, but I'll mention it as softly as I can. There were some people that went down looking for the Titanic recently. It could have worked, you know what I mean? These are risks we all take.

I think this perspective is better characterized as “solo” and not “old”. I don’t think your age is relevant here.
Senior engineers are not necessarily old but have the experience to delegate manageable tasks to peers including juniors and collaborate with stakeholders. They’re part of an organization by definition. They’re senior to their peers in terms of experience or knowledge, not age.
Agentic AIs slot into this pattern easily.
If you are a solo dev you may not find this valuable. If you are a senior then you probably do.

One benefit is when working on multiple code bases where the size of the code base is larger than the time spent working on it, so there is still a gap of knowledge. Agents don't guarantee the correctness of a search the same an old search field does, but it offers a much more expressive way to do searches and queries in a code base.
Now that I think about it, I might have only ever used agents for searching and answering questions, not for producing code. Perhaps I don't trust the AI to build a good enough structure, so while I'll use AI, it is one file at a time sort of interaction where I see every change it makes. I should probably try out one of these agent based models for a throw away project just to get more anecdotes to base my opinion on.
jmvldz · 5h ago
Coding agents are the future and it's anyone's game right now.
The main reason I think there is such a proliferation is it's not clear what the best interface to coding agents will be. Is it in Slack and Linear? Is it on the CLI? Is it a web interface with a code editor? Is it VS Code or Zed?
Just like everyone has their favored IDE, in a few years time, I think everyone will have their favored interaction pattern for coding agents.
Product managers might like Devin because they don't need to setup an environment. Software engineers might still prefer Cursor because they want to edit the code and run tests on their own.
Cursor has a concept of a shadow workspace and I think we're going to see this across all coding agents. You kick off an async task in whatever IDE you use and it presents the results of the agent in an easy to review way a bit later.
As for Void, I think being open source is valuable on it's own. My understanding is Microsoft could enforce license restrictions at some point down the road to make Cursor difficult to use with certain extensions.
I'm working on an agnostic unified framework to make contexts transferrable between these tools.
This will permit zero friction, zero interruption transitions without any code modification.
Should have something to show by next week.
Hit me up if you're interested in working on this problem - I'm tired of cowboying my projects.

I've tried many of AI coding IDE's, the best ones like RooCode are good simply because they don't gimp your context. The modern day models are already more then capable enough for many coding tasks, you just need to leave them alone and let them utilize their full context window and all will go well. If you hear a bad experience with any of these IDE's, most of the time its because its limiting use of context or improper management of related functions.

One of the founders here - Void will always remain open source! There are plenty of examples of an open source alternative finding its own niche (eg Supabase, Mattermost) and we don't see this being any different.
I've been at many open source meetups with YC founders and can tell you that this is not the thinking at all. Rather, the emphasis is on finding a good carve-line between the open source offering and the (eventual) paid one, so that both sides are viable and can thrive.
Most common these days is to make the paid product be a hosted version of the open source software, but there are other ways too. Experienced founders emphasize to new startups how important it is to get this right and to keep your open source community happy.
No one I've heard is treating open source like a bait and switch; quite the opposite. What is sought is a win-win where each component (open source and paid) does better because of the other.
danenania · 4h ago
Exactly right.
I think there’s a general misconception out there that open sourcing will cannibalize your hosted product business if you make it too easy to run. But in practice, there’s not a lot of overlap between people who want to self-host and people who want cloud. Most people who want cloud still want it even if they can self-host with a single command.

Thanks for writing! Can you try mentioning the file with "@"? Smaller models sometimes don't realize that they should look for files and folders, but "@" always gives the full context of whatever is in the file/folder directly to them.

minzi · 56m ago
Its agent is a lot worse than Cursor's in my experience so far. Even tab edits feel worse.
My understanding is that these are not custom models but a combination of prompting and steering. That makes Cursor's performance relative to others pretty surprising to me. Are they just making more requests? I wonder what the secret sauce is.

One thing I noticed is that there's no cost tracking, so it's very hard to predict how much you're spending. This is fine on tools like Cursor that are all inclusive, but is something that is really necessary if you're bringing your own API keys.
Is this feature on the roadmap?
mp5 · 39m ago
This is a great suggestion. We're actually storing the input/output costs of most models, but aren't computing cost estimates yet. Definitely something to add. My only hesitation is that token-based cost estimates may not be accurate (most models do not provide their tokenizers, so you have to eg. estimate the average number of characters per token in order to compute the cost, and this may vary per model).

As a data scientist, my main gripe with all these AI-centric IDEs is that they don’t provide data centric tools for exploring complex data structures inherent to data science. AI cannot tell me about my data, only my code.
I’ll be sticking with VSCode until:
- Notebooks are first class objects. I develop Python packages but notebooks are essential for scratch work in data centric workflows
- I can explore at least 2D data structures interactively (including parquet). The Data Wrangler in VSCode is great for this

Is there some benefit from forking vscode instead of creating an extension?
andrewpareles · 5h ago
Void dev here! As others have mentioned, VSCode strongly limits the functionality that you can build as an extension. A few things we've built that aren't supported as an extension:
- the Accept|Reject UI and UX
- Cmd+K
- Control over the terminal and tabs
- Custom autocomplete
- Smaller things like ability to open/close the sidebar, onboarding, etc
It's been a lot harder to build an IDE than an extension, but we think having full control over the IDE (whether that's VSCode or something else we build in the future) will be important in the long run, especially when the next iteration of tool-use LLMs comes out (having native control over Git, the UI/UX around switching between iterations, etc).
mentalgear · 5h ago
the Accept|Reject UI and UX , Continue as a VS Code extension also seems to manage this
johnfn · 6h ago
As an (ex) VSCode extension developer, VSCode really does lock down what you can do as an extension. It's well intentioned and likely led to the success of VSCode, but it's not great if you want to build entirely new UI interactions. For instance, something like the cmd-k inline generation UI in Cursor is basically impossible as a VSCode extension.
gman83 · 6h ago
People keep saying that the extensions API is too limited or something, but Cline seems to manage fine with being an extension.

You're right that extensions do manage fine - the main differences right now are UX improvements (many of them are mentioned above). I can see the differences compounding at some point which is why we're focused on the full IDE side.

One of the big _disadvantages_ is that it prevents access to the VSCode-licensed plugins, such as the good C# LSP (seems EEE isn't completely dead). That's something to pay attention to if you're considering a fork and use an affected language.
jsheard · 5h ago
Since these products supposedly make developers 1000x more productive it should be no problem to just re-implement those proprietary MS plugins from scratch. Right? Any volunteers...?
manmal · 4h ago
MS will be tuning Copilot to the point it’s the best agent for C#, for sure. It might take a little longer ofc. But Nadella mentioned to Zuck in a fireside chat that they are not happy with C# support in LLMs and that they are working on this.
Did you mean to say a debugger? That one has an open alternative (NetCoreDbg) alongside a C# extension fork which uses it (it's also what VS Codium would install). It's also what you'd use via DAP with Neovim, Emacs, etc.
danenania · 4h ago
I wish all these companies the best and I understand why they’re forking, but personally I really don’t want my main IDE maintained by a startup, especially as a fork. I use Cursor, and I’ve run into a number of bugs at the IDE level that have nothing to do with the AI features. I imagine this is only going to get worse over time.
MortyWaves · 6h ago

well you got downvoted, but it's not wrong: funding attractiveness of an extension (Cline) vs your "own IDE".
johnfn · 6h ago
This is very cool and I'm always happy to see more competition in this space. That said, two suggestions:
- The logo looks like it was inspired directly from the Cursor logo and modified slightly. I would suggest changing it.
- It might be wise to brand yourself as your own thing, not just an "open source Cursor". I tend to have the expectation that "open source [X]" projects are worse than "[X]". Probably unfair, I know.
mp5 · 4h ago
Thanks for the suggestions - these issues have been a bit painful for us, and we will probably fix them in the next major update to Void.
Believe it or not, the logo similarity was actually unintentional, though I imagine there was subconscious bias at play (we created ours trying to illustrate "a slice of the Void").
freedomben · 5h ago
A minor counterpoint, I personally like the "open source Xyz" because I instantly know what the product is supposed to do. It's also very SEO friendly because you don't know the name of the open source version before you find it, so you can Kagi/Google/DDG "open source Cursor" and get it as a top result, instead of a sea of spammy slime.
May I ask why did you decide against starting with (Eclipse) Theia instead of VSCode?
It's compatible but has better integration and modularity, and doing so might insulate you a bit from your rather large competitor controlling your destiny.
Or is the exit to be bought by Microsoft? By OpenAI? And thus to more closely integrate?
If you're open-source but derivative, can they not simply steal your ideas? Or will your value depend on having a lasting hold on your customers?
I'm really happy there are full-fledged IDE alternatives, but I find the hub-and-spoke model where VSCode/MS is the only decider of integration patterns is a real problem. LSP has been a race to the bottom, feature-wise, though it really simplified IDE support for small languages.
MantisShrimp90 · 4h ago
Projects like this are great because open source versions need to figure out the right way to do things, rather than the hacky, closed, proprietary alternatives that pop up first and are just trying to consume as many users as possible to get a most quickly.
In that case, a shitty, closed system is good actually because it's another thing your users will need to "give up" if they move to an alternative. By contrast, an open ide like void will hopefully make headway on an open interface between ides and the llm agents in such a way that it can be adapted by neovim people like me or anyone else for that matter

There is no plan with YC in this space, everything is just basically vibe investing and hoping something sticks.
Continue.dev also received investment from YC. Remember PearAI? Very charismatic founders that just forked Continue.dev and got a YC investment [1].
This is a good question. Because we're open source, we will always allow you to host models locally for free, or use your own API key. This makes monetization a bit difficult in the short term. As with many devtool companies, the long-term value comes from enterprise sales.
_pdp_ · 2h ago
On a tangent, I get the feeling that the more senior you are, the less likely you are to end up using one of these VIDEs. If you do use any coding assistants at all, it will mostly be for the auto-complete feature - no 'agent mode' malarkey.
Would you say this is true?
codybontecou · 2h ago
Maybe it's just me, but the auto-complete is very distracting and something I avoid. Most of the time I'm fighting it, deleting or denying it's suggestions, and it throws me out of flow.
From what I've seen, most senior/staff-level engineers are working for big corps which have limited contracts with providers like Github Copilot, which until recently only gave access to autocomplete.
I prefer the web-based interface. It feels like my choice to reference a tool. It's easy to run multiple chats at once, running prompts against multiple models.
_pdp_ · 1h ago
That's very interesting. This is certainly what I was doing before Copilot. Now I let it autocomplete but only sometimes when it makes sense. I guess I am used to the keybinds so that I can undo if I don't like it.
When I was reading your comment I thought that there is a space for an out-of-flow coding assistant, i.e. rather than deploy an entire IDE with extension, the assistant can be just a floating window (I guess chatgpt does that) and is able to dive in and out or just suggest as you type along.

Given that there's a dozen agentic coding IDEs, I only use Cursor because of the few features they have like auto-identification of the next cursor location (I find myself hitting tab-tab-tab-tab a lot, it speeds up repetitive edits). Are there any other IDEs that implement these QOL features, including Void (given it touts itself specifically as a Cursor alternative)?
ramoz · 4h ago
I think QOL will shift away from your keyboard. Give Claude Code a try and you’ll understand what I mean. Developer UX will shift away from traditional IDEs. At this point I could use notepad for the the type of manual work I do vs how I orchestrate Claude Code.

skydhash · 2h ago
I get your experience, but for me using vim is perfect for code exploration. The only needed plugins are fzf.vim and vinegar. The first for fuzzy navigation and the second for quickly browsing the current directory.
LSP experience with VSCode may be superior, but if I truly needed that, I would get an IDE and have proper intellisense. The LSP in Vim and Emacs is more than enough for my basic requirements, which are auto-imports, basic linting, and autocomplete to avoid misspellings. VSCode lacks Vim's agility and Emacs's powerful text tooling, and do far worse on integration.
kurtis_reed · 6h ago
what sorts of things are hard to configure?
spauldo · 5h ago
Emacs' configurability is hard to describe to anyone who hasn't immersed themselves in that sort of environment. There's a small portion of the program written C, but the bulk of it is written in elisp. When you evaluate elisp code, you're not in some sandboxed extension system - you're at the same level as Emacs itself. This allows you to modify nearly any aspect of Emacs.
It'd be a security nightmare if it was more popular, but fortunately the community hovers around being big enough for serious work to be done but small enough that it's not worth writing malware for.
Buttons840 · 31m ago
I don't know if it's a security nightmare any more than other editors that have "plugins" (or the like).
One advantage for Emacs is it's both easy and common read the code of the plugins you are using. I can't tell you the last time I looked at the source code of a plugin for VS Code or any other editor. The last time I looked at the code for a plugin in Emacs was today.
skydhash · 2h ago
I don't think it's a security nightmare per-se. Most of the time, you're not installing a lot of packages (the built-in are extensive) and most of these are small and commonly used.
It's like saying the AUR is a security nightmare. You're just expected to be an adult and vet what you're using.

Mandatory reminder that "agentic coding" works way worse than just using the LLM directly, steering it ad needed, filling the gaps, and so forth. The value is in the semantical capabilities of the LLM itself: wrapping it will make it more convenient to use, but always less powerful.
rcarmo · 5h ago
I beg to disagree, Salvatore... Have a go at VS Code with Agent mode turned on (you'll need a paid plan to use Claude and/or Gemini, I think). It gets me out of vim, so yeah, it's that good. :)
Tip: Write a SPEC.md file first. Ask the LLM to ask _you_ about what might be missing from the spec, and once you "agree" ask it to update the SPEC.md or create a TODO.md.
Then iterate on the code. Ask it to implement one of the features, hand-tune and ask it to check things against the SPEC.md and update both files as needed.
Works great for me, especially when refactoring--the SPEC.md grounds Claude enough for it not to go off-road. Gemini is a bit more random...
antirez · 4h ago
Interacting with the LLM directly is more work. What I mean is that a wrapper in the best conditions will not damage too much the quality of the LLM itself. In the chat, you continuously avoid suboptimal choices executed by the model, if you are a very experienced code, and a fix here, a fix there, you continuously avoid local minima. After a few iterations you find that your whole project is a lot better designed than otherwise.
rcarmo · 4h ago
Oh, sure. I don't rely on the LLM to write all the code. I do "trust" it to refactor things to a shape I want, and to automate chores like moving chunks of code around or build a quick wrapper for a library.
One thing I particularly don't like about LLMs is that their Python code feels like Java cosplay (full of pointless classes and methods), so my SPEC.md usually has a section on code style right at the start :)

The best reason I‘ve seen mentioned by the founder in this thread, is showing/hiding panels, and the onboarding flow. Those are things you can’t do with a plugin. I personally also like Cursor‘s diff view way better than Continue‘s, and maybe that’s because a fork gives more control there.

Great to see more people thinking this way, finally. Would be even better to see the same change wrt typescript, another MS trojan horse.
But it's a different take, Brokk is built to let humans supervise AI more effectively rather than optimizing for humans reading and writing code by hand. So it's not a VS Code fork, it's not really an IDE in the traditional sense at all.

But I do stand by the point. We are seeing umpteen of these things launched every week now, all with the exact same goal in mind; monetizing a thin layer of abstraction between code repos and model providers, to lock enterprises in and sell out as quickly as possible. None of them are proposing anything new or unique above the half dozen open source extensions out there that have gained real community support and are pushing the capabilities forward. Anyone who actually uses agentic coding tools professionally knows that Windsurf is a joke compared to Cline, and that there is no good reason whatsoever for them to have forked. This just poisons the well further for folks who haven't used one yet.

As a non-Cursor user who does AI programming, there is nothing there to make me want to try it out.
Feedback 2: I feel any new agentic AI tool for programming should have a comparison against Aider[1] which for me is the tool to benchmark against. Can you give a compelling reason to use this over Aider? Don't just say "VSCode" - I'm sure there are extensions for VSCode that work with Aider.
As an example of the questions I have:
- Does it have something like Aider's repomap (or better)?
- To what granularity can I limit the context?
[1] https://aider.chat/
We don't have a repomap or codebase summary - right now we're relying on .voidrules and Gather/Agent mode to look around to implement large edits, and we find that works decently well, although we might add something like an auto-summary or Aider's repomap before exiting Beta.
Regarding context - you can customize the context window and reserved amount of token space for each model. You can also use "@ to mention" to include entire files and folders, limited to the context window length. (you can also customize the model's reasoning ability, think tags to parse, tool use format (gemini/openai/anthropic), FIM support, etc).
Back in 2023 one of the cursor devs mentioned [1] that they first convert the HTML to markdown then do n-gram deduplication to remove nav, headers, and footers. The state of the art for chunking has probably gotten a lot better though.
[1] https://forum.cursor.com/t/how-does-docs-crawling-work/264/3
I wonder if the next round of models trained on tool-use will be good at looking at documentation. That might solve the problem completely, although OSS and offline models will need another solution. We're definitely open to trying things out here, and will likely add a browser-using docs scraper before exiting Beta.
That's all in the website, not the README, but yes a bulleted list or identical info from the site would work well.
If nearly everytime I use it to accomplish something it gets it 40-85% correct and I have to go in to fix the other 60-15%, what is the point? It's as slow as hand writing code then, if not slower, and my flow with Continue is simply better:
1. CTRL L block of code 2. Ask a question or give a task 3. I read what it says and then apply the change myself by CTRL C and then tweaking the one or two little things it inevitably misunderstood about my system and its requirements
Aider's killer features are integration of automated lint/typecheck/test and fix loops with git checkpointing. If you're not setting up these features you aren't getting the full value proposition from it.
Use gemini-2.5pro or sonnet3.5/3.7 or gpt-4.1
Be as specific and detailed in your prompts as you can. Include the right context.
I'm getting really tired of AI advocates telling me that AI is as good as the hype if I just pay more (say, fellow HNer, your paycheck doesn't come from those models, does it?), or use the "right" prompt. Give some examples.
If I have to write a prompt as long as Claude's system prompt in order to get reliable edits, I'm not sure I've saved any time at all.
At least you seem to be admitting that aider is useless with local models. That's certainly my experience.
I don't see it as an admission. I'd wager 99% of Aider users simply haven't tried local models.
Although I would expect they would be much worse than Sonnet, etc.
> I'm getting really tired of AI advocates telling me that AI is as good as the hype if I just pay more (say, fellow HNer, your paycheck doesn't come from those models, does it?), or use the "right" prompt. Give some examples.
Examples? Aider is a great tool and much (probably most) of it is written by AI.
Perhaps when it can dynamically learn on the go this will be better. But right now it's not terribly useful.
I've tested aider with gemini2.5 with prompts as basic as 'write a ts file with pupeteer to load this url, click on button identified by x, fill in input y, loop over these urls' and it performed remarkably well.
Llm performance is 100% dependent on the model you're using so you ca hardly generalize from a small model you run locally on a cpu.
There are certainly a lot of alternatives that are plugins(!), but our differentiation right now is being a full open source IDE and having all the features you get out of the big players (quick edits, agent mode, autocomplete, checkpoints).
Surprisingly, all of the big IDEs today (Cursor/Windsurf/Copilot) send your messages through their backend whenever you send a message, and there is no open source full IDE alternative (besides Void). Your connection to providers is direct with Void, and it's a lot easier to spin up your own models/providers and host locally or use whatever provider you want.
We're planning on building Git branching for agents in the next iteration when LLMs are more independent, and controlling the full IDE experience for that will be really important. I worry plugins will struggle.
And Zed: https://zed.dev
Yesterday on the front page of HN:
https://news.ycombinator.com/item?id=43912844
Claude Code (neither IDE nor extension) is rapidly gaining ground, it's biggest current limitation being cost, which is likely to get resolved sooner rather than later (Gemini Code anyone?). You're right about the right now, but with the pace at which things are moving, the trends are honestly more relevant than the status quo.
We think in 1-2 years people will write code at a systems level, not a function level, and it's not clear to us that you can do that with text. Text-based tools like Claude Code work in our text-based-code systems today, but I think describing algorithms to a computer in the future might involve more diagrams, and terminal will not be ideal. That's our reasoning against building a tool in the terminal, but it clearly works well today, and is the simplest way for the labs to train/run terminal tool-use agents.
What makes you say that? From what I’m observing it doesn’t seem to be talked much about at all.

For real. I think it's because code editors seem to be in that perfect intersection of:
- A tool for programmers. Programmers like building for programmers.
- A tool for productivity. Companies will pay for productivity.
- A tool that's clearly AI-able. VC's will invest in AI tools.
- A tool with plenty of open source lift. The clear, common (and extreme?) example of this being forking VSCode.
Add to that the recent purchase of VSCode-fork [1] Windsurf for $3 billion [2] and I suspect we will see many more of these.

Context switching is not the bottleneck. I actually like to go away from the IDE/keyboard to think through problems in a different environment (so a voice version of chatgpt that I can talk to via my smartwatch while walking and see some answers either on my smartglasses or via sound would be ideal… I don’t really need more screen (monitor) time)
I do this all the time, and I am completely fine with it. Sure, I need to pay more attention, but I think it does more good than harm.
For well trodden paths that AI is good at, you're wasting a ton of time copying context and lint/typechecking/test results and copying back edits. You could probably double your productivity by having an agentic coding workflow in the background doing stuff that's easy while you manually focus on harder problems, or just managing two agents that are working on easy code.
At it's most basic, agentic mode is necessary for building the proper context. While I might know the solution at the high level, I need the agent to explore the code base to find things I reference and bring them into context before writing code.
Agentic mode is also super helpful for getting LLMs from "99%" correct code to "100%" correct code. I'll ask them to do something to verify their work. This is often when the agent realizes it hallucinated a method name or used a directionally correct, but wrong column name.
1) Authority (whatever a prominent evangelist developer was peddling)
2) The book I was following as a guide
3) The tutorial I was following as a guide
4) The consensus of the crowd at the time
5) Whatever worked (SO, brute force, whatever library, whatever magic)
It took a long ass time before I got to throw all five of those things out (throw the map away). At the moment, #5 on that list is AI (whatever works). It's a Rite of Passage, and because so much of being a developer involves autodidacticism, this is a valley you must go through. Even so, it's pretty cool when you make it out of that valley (you can do whatever you want without any anxiety about is this the right path?). You are never fearful or lost in the valley(s) for the most part afterward.
Most people have not deployed enough critical code that was mostly written with AI. It's when that stuff breaks, and they have to debug it with AI, that's when they'll have to contend with the blood, sweat, and tears. That's when the person will swear that they'll never use AI again. The thing is, we can never not use AI ever again. So, this is the trial by fire where many will figure out the depth of the valley and emerge from it with all the lessons. I can only speculate, but I suspect the lessons will be something along the lines of "some things should use less AI than others".
I think it's a cool journey, best of luck to the AI-first crowd, you will learn lessons the rest of us are not brave enough to embark on. I already have a basket of lessons, so I travel differently through the valley (hint: My ship still has a helm).
Or, most software will become immutable. You'll just replace it.
You'll throw away the mess, and let a newer LLM build a better version in a couple of days. You ask the LLM to write down the specs for the newer version based on the old code.
If that is true, then the crowd that is not brave enough to do AI-first will just be left behind.
The joys of dependency hell combined with rapid deprecation of the underlying tooling.
Not even, devoured might be more apt. If I'm manually moving through this valley and a flood is coming through, those who are sticking automatic propellers and navigation systems on their ship are going to be the ones that can surf the flood and come out of the valley. We don't know, this is literally the adventure. I'm personally on the side of a hybrid approach. It's fun as hell, best of luck to everyone.
It's in poor taste to bring up this example, but I'll mention it as softly as I can. There were some people that went down looking for the Titanic recently. It could have worked, you know what I mean? These are risks we all take.
Quoting the Admiral from Starcraft Broodwars cinematic (I'm a learned person):
"... You must go into this with both eyes open"
I actually flip things - I do the breakdown myself in a SPEC.md file and then have the agent work through it. Markdown checklists work great, and the agent can usually update/expand them as it goes.
Senior engineers are not necessarily old but have the experience to delegate manageable tasks to peers including juniors and collaborate with stakeholders. They’re part of an organization by definition. They’re senior to their peers in terms of experience or knowledge, not age.
Agentic AIs slot into this pattern easily.
If you are a solo dev you may not find this valuable. If you are a senior then you probably do.
Now that I think about it, I might have only ever used agents for searching and answering questions, not for producing code. Perhaps I don't trust the AI to build a good enough structure, so while I'll use AI, it is one file at a time sort of interaction where I see every change it makes. I should probably try out one of these agent based models for a throw away project just to get more anecdotes to base my opinion on.
The main reason I think there is such a proliferation is it's not clear what the best interface to coding agents will be. Is it in Slack and Linear? Is it on the CLI? Is it a web interface with a code editor? Is it VS Code or Zed?
Just like everyone has their favored IDE, in a few years time, I think everyone will have their favored interaction pattern for coding agents.
Product managers might like Devin because they don't need to setup an environment. Software engineers might still prefer Cursor because they want to edit the code and run tests on their own.
Cursor has a concept of a shadow workspace and I think we're going to see this across all coding agents. You kick off an async task in whatever IDE you use and it presents the results of the agent in an easy to review way a bit later.
As for Void, I think being open source is valuable on it's own. My understanding is Microsoft could enforce license restrictions at some point down the road to make Cursor difficult to use with certain extensions.
Another YC backed open source VS Code is Continue: https://www.continue.dev/
(Caveat: I am a YC founder building in this space: https://www.engines.dev/)
I'm working on an agnostic unified framework to make contexts transferrable between these tools.
This will permit zero friction, zero interruption transitions without any code modification.
Should have something to show by next week.
Hit me up if you're interested in working on this problem - I'm tired of cowboying my projects.
I know some folks like using the terminal, but if you like Claude Code you should consider plugging your API key into Void and using Claude there! Same exact model and provider and price, but with a UI around the tool calls, checkpoints, etc.
That is until I started using Claude Code.
It’s not about the terminal. It’s just a better UX in general.

Most common these days is to make the paid product be a hosted version of the open source software, but there are other ways too. Experienced founders emphasize to new startups how important it is to get this right and to keep your open source community happy.
No one I've heard is treating open source like a bait and switch; quite the opposite. What is sought is a win-win where each component (open source and paid) does better because of the other.
I think there’s a general misconception out there that open sourcing will cannibalize your hosted product business if you make it too easy to run. But in practice, there’s not a lot of overlap between people who want to self-host and people who want cloud. Most people who want cloud still want it even if they can self-host with a single command.
The effort required to start Cursor is the reason I don't use it much. VS code is an actual, bona fide installed app with an icon that sits on my screen, I just click it to launch it. So much easier. Even if I have to write code manually.
I'm still in vim with copilot and know I'm missing out. Anyway I'm also adding to the problem as I've got my own too (don't we all?!), at https://codeplusequalsai.com. Coded in vim 'cause I can't decide on an editor!
Then I opened an existing file and asked it to modify a function to return a fixed value and it did the same.
I'm an absolute newb in this space so if I'm doing something stupid I'd appreciate it if you helped me correct it because I already had the C/C++ extension complain that it can only be used in "proper vscode" (I imported my settings from vscode using the wizard) and when this didn't work either it didn't spark joy as Marie Kondo would say.
Please don't get me wrong, I gave this a try because I like the idea of having a proper local open source IDE where I can run my own models (even if it's slower) and have control over my data. I'm genuinely interested in making this work.
Thanks!
Small OSS models are going to get better at this when there's more of a focus on tool-use, which we're expecting in the next iteration of models.
My understanding is that these are not custom models but a combination of prompting and steering. That makes Cursor's performance relative to others pretty surprising to me. Are they just making more requests? I wonder what the secret sauce is.
Is this feature on the roadmap?
I’ll be sticking with VSCode until:
- Notebooks are first class objects. I develop Python packages but notebooks are essential for scratch work in data centric workflows
- I can explore at least 2D data structures interactively (including parquet). The Data Wrangler in VSCode is great for this
It's been a lot harder to build an IDE than an extension, but we think having full control over the IDE (whether that's VSCode or something else we build in the future) will be important in the long run, especially when the next iteration of tool-use LLMs comes out (having native control over Git, the UI/UX around switching between iterations, etc).
Did you mean to say a debugger? That one has an open alternative (NetCoreDbg) alongside a C# extension fork which uses it (it's also what VS Codium would install). It's also what you'd use via DAP with Neovim, Emacs, etc.
- The logo looks like it was inspired directly from the Cursor logo and modified slightly. I would suggest changing it.
- It might be wise to brand yourself as your own thing, not just an "open source Cursor". I tend to have the expectation that "open source [X]" projects are worse than "[X]". Probably unfair, I know.
Believe it or not, the logo similarity was actually unintentional, though I imagine there was subconscious bias at play (we created ours trying to illustrate "a slice of the Void").
Show HN: Void, an open-source Cursor/GitHub Copilot alternative - https://news.ycombinator.com/item?id=41563958 - Sept 2024 (154 comments)
It's compatible but has better integration and modularity, and doing so might insulate you a bit from your rather large competitor controlling your destiny.
Or is the exit to be bought by Microsoft? By OpenAI? And thus to more closely integrate?
If you're open-source but derivative, can they not simply steal your ideas? Or will your value depend on having a lasting hold on your customers?
I'm really happy there are full-fledged IDE alternatives, but I find the hub-and-spoke model where VSCode/MS is the only decider of integration patterns is a real problem. LSP has been a race to the bottom, feature-wise, though it really simplified IDE support for small languages.
In that case, a shitty, closed system is good actually because it's another thing your users will need to "give up" if they move to an alternative. By contrast, an open ide like void will hopefully make headway on an open interface between ides and the llm agents in such a way that it can be adapted by neovim people like me or anyone else for that matter
Continue.dev also received investment from YC. Remember PearAI? Very charismatic founders that just forked Continue.dev and got a YC investment [1].

Would you say this is true?
From what I've seen, most senior/staff-level engineers are working for big corps which have limited contracts with providers like Github Copilot, which until recently only gave access to autocomplete.
I prefer the web-based interface. It feels like my choice to reference a tool. It's easy to run multiple chats at once, running prompts against multiple models.
When I was reading your comment I thought that there is a space for an out-of-flow coding assistant, i.e. rather than deploy an entire IDE with extension, the assistant can be just a floating window (I guess chatgpt does that) and is able to dive in and out or just suggest as you type along.

Over the years I have gotten better with vim, added phpactor and other tooling, but frankly i dont have time to futz and its not so polished. With VSCode I can just work. I don't love everything about it, but it works well enough with copilot i forgot the benefits of vim.
LSP experience with VSCode may be superior, but if I truly needed that, I would get an IDE and have proper intellisense. The LSP in Vim and Emacs is more than enough for my basic requirements, which are auto-imports, basic linting, and autocomplete to avoid misspellings. VSCode lacks Vim's agility and Emacs's powerful text tooling, and do far worse on integration.
It'd be a security nightmare if it was more popular, but fortunately the community hovers around being big enough for serious work to be done but small enough that it's not worth writing malware for.
One advantage for Emacs is it's both easy and common read the code of the plugins you are using. I can't tell you the last time I looked at the source code of a plugin for VS Code or any other editor. The last time I looked at the code for a plugin in Emacs was today.
It's like saying the AUR is a security nightmare. You're just expected to be an adult and vet what you're using.
One thing i'd really like to have is a manual order for folders or even files in the explorer view.

If you're all in on Claude then yeah, just go direct. Going through a proxy of silly
Ycombinator backed too I guess Vibe coding is here to stay
Oh wow, I didn't even realize. Substantially less appealing of a project to me now.
We live in the age of dev tools
Tip: Write a SPEC.md file first. Ask the LLM to ask _you_ about what might be missing from the spec, and once you "agree" ask it to update the SPEC.md or create a TODO.md.
Then iterate on the code. Ask it to implement one of the features, hand-tune and ask it to check things against the SPEC.md and update both files as needed.
Works great for me, especially when refactoring--the SPEC.md grounds Claude enough for it not to go off-road. Gemini is a bit more random...
One thing I particularly don't like about LLMs is that their Python code feels like Java cosplay (full of pointless classes and methods), so my SPEC.md usually has a section on code style right at the start :)

Additionally, Zed is written in Rust and has robust hardware-accelerated rendering. This has a tangible feel that other editors do not. It feels just so smooth, unlike clunky heavyweight JetBrains products. And it feels solid and sturdy, unlike VS Code buffers, which feel like creaky webviews.
But it's a different take, Brokk is built to let humans supervise AI more effectively rather than optimizing for humans reading and writing code by hand. So it's not a VS Code fork, it's not really an IDE in the traditional sense at all.

What I want is to be able to do is.
1. Create a branch called TaskForLLM_123 2. Add a file with text instructions called Instructions_TaskForLLM_123.txt 3. Have a GitHub action read the branch, perform the task and then submit a PR.
We're trying for thoughtful, respectful discussion of people's work on this site. Snarky, nasty oneliners destroy that.
We detached this subthread from https://news.ycombinator.com/item?id=43928512.
But I do stand by the point. We are seeing umpteen of these things launched every week now, all with the exact same goal in mind; monetizing a thin layer of abstraction between code repos and model providers, to lock enterprises in and sell out as quickly as possible. None of them are proposing anything new or unique above the half dozen open source extensions out there that have gained real community support and are pushing the capabilities forward. Anyone who actually uses agentic coding tools professionally knows that Windsurf is a joke compared to Cline, and that there is no good reason whatsoever for them to have forked. This just poisons the well further for folks who haven't used one yet.
I would still push back on this:
> all with the exact same goal in mind
It seems to me that you're assuming too much about other people's intentions, jumping beyond what you can possibly know. When people do that to reduce things to a cynical endstate before they even get off the ground, that's not good for either discussion or community. This is part of the reason why we have guidelines like these in https://news.ycombinator.com/newsguidelines.html:
"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
"Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative."
Next big sale is going to be something like "Chrome Fork + AI + integrated inter-app MCP". Brave is eh, Arc is being left to die on its own, and Firefox is... doing nothing.
