Show HN: Dyad, local, open-source Lovable alternative (Electron desktop app)

Hi HN!

I left Google earlier this year and created Dyad, a local, open-source AI app builder made with Electron.

The motivation: I tried one of the popular cloud-based AI app builders, but when I pulled down the app to run locally and debug in Cursor, it just didn’t work. So I created Dyad, an app builder that runs fully on your computer, making it easy to switch between Dyad and coding tools like Cursor or Claude Code.

Source code: https://github.com/dyad-sh/dyad/

Download (free, no sign-up): https://www.dyad.sh/

I've gotten questions about how it works under the hood so I wrote an architecture doc explaining how it does tool calling using XML tags, etc: https://github.com/dyad-sh/dyad/blob/main/docs/architecture....

Let me know what you think and happy to answer questions about building an Electron app, etc!

Congrats for launching and awesome work, I will try it out soon!

Question, I have my own persistence and auth services, all well documented, that I would like to build apps against. Is there a recommended way to do this other than pasting the docs in the prompt each time I create a new app?

These things does work (up to a max few thousand lines of code), but, they eat tokens like f*ng monsters.

I'm working on adding MCP support to Dyad soon! What's your favorite MCP servers? (trying to curate a list of recommended MCPs)
