Ask HN: Merge Request Review Agent?

3 surrTurr 5 5/27/2025, 4:49:40 PM
Looking for an agent that I can use to create a MR review for MRs e.g. on GitLab.

The agent should review the changes using (1) git diff (2) rag on codebase (3) other sources, e.g. web

Yes, I could build this myself using e.g. langchain; however, I think this has been built hundrets of times by now; therefore my question: are there any ready to use agents for this kind of task?

I couldn't find an email in your profile, so feel free to shoot me a message instead? (you can find my email on my profile page ;) ). I'm currently building a startup (https://codeinput.com) focused on merge request workflows - handling conflicts, reviews, queues, and all the related pain points - and open to hear and get in touch with other developers who are interested in these tools.

Here is a list of a few tools that do something like that: jazzberry ai, greptile, coderabbit, codeant (lots of code), cubic, qodo.

GitLab may also have a code review tool available now (I know that GitHub does)

GitLab Duo is available in Merge Requests and can do reviews (and other tasks, as well): https://docs.gitlab.com/user/project/merge_requests/duo_in_m...

Hey, I’m part of the Kodus team. We built an open source code review agent. It’d be awesome if you gave it a try. Here’s the repo (https://github.com/kodustech/kodus-ai)
