Crit – a local review tool for agent plans and code diffs.

Technical Positioning

A CLI tool that provides a GitHub-inspired browser interface for reviewing agent-generated plans and code diffs locally, facilitating iterative feedback with agents before committing to GitHub. Offers optional self-hostable hosted service for team feedback.

SaaS Insight & Market Implications

Crit addresses a critical gap in the AI-assisted development workflow: effective review of agent-generated output. As agents become more prevalent in generating code and plans, developers need robust tools to inspect, provide feedback, and iterate. Crit's local, browser-based, GitHub-inspired interface provides a familiar and efficient environment for this. The ability to "juggle parallel conversations with agents" and review "before it hits GitHub" directly improves developer productivity and code quality. The optional self-hostable team feedback mechanism further enhances its utility for collaborative environments. This tool is well-positioned within the emerging ecosystem of AI agent tooling, focusing on human-agent collaboration and quality assurance.

Show HN: Crit – local review tool for agent plans and code diffs

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.

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 firstI 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

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.

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!

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!
