Crit is a single-binary CLI that opens your file or code diffs in a browser with GitHub-inspired interface. Your favourite agent acts on the feedback and responds back - continue until you're happy.

I've been building this for a few months now and it's been helping me a lot juggling parallel conversations with agents, making it easier to actually review the plans they generate and the resulting code - all before it hits GitHub.

It also allows you to export the plans to a hosted service (which you can self-host for privacy), to solicit feedback from your team. No account needed, and reviews are automatically deleted after 30 days of inactivity.

On a personal note, as this is my first proper OSS project, I'm very humbled by the response and the feedback from the users! And it made me realise I need to be reaching out to maintainers of OSS work I rely on more and thank them!

I've been using crit since very early on and it's become an invaluable tool in my arsenal since day one. It really fills that niche of reviewing agent work easily and painlessly.

Thanks for building this and for being so attentive to feedback, Tomasz!

I've been using crit daily for the last several weeks (using it for 5–10 plans/day). I'm a big fan - it fills a major gap in Claude Code for me as I migrate from Cursor.

crit was a game changer for my longer planning sessions and it gives me a good way to do code review for llm output locally first

I was anticipating setting up gitea or something and using that as a place where I'd push code while I was still iterating but thanks to crit I totally avoid that!

just fits into my workflow too
