Ask HN: Merge Request Review Agent?

by surrTurr on 5/27/2025, 4:49:40 PM with 6 comments
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?

    Why not just get rid of the review entirely?

    An AI is never going to understand the subtleties of the MR with respect to business goals of the application.

    As to the others here working on similar things, I weep for the future.

    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)

    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.
