CodeRabbit

AI code reviews that cut review time and bugs in half — context-aware, line-by-line feedback on every PR.

What is CodeRabbit?

CodeRabbit is an AI code review tool that automatically reviews every pull request with context-aware, line-by-line feedback. It installs on GitHub, GitLab, or Azure DevOps in a couple of clicks, then posts PR summaries, sequence diagrams, and concrete code suggestions you can commit directly. Unlike simple linters, CodeRabbit learns your repository's context and your team's conventions over time, and you can chat with it inside the PR to refine suggestions or generate fixes. It layers static analyzers and security scanners on top of its AI review, catching bugs, vulnerabilities, and style issues before a human reviewer looks at the code. Reviews also run in the CLI and IDE for pre-commit feedback. The tool is free for open-source repositories, with paid per-seat plans for private ones — a fit for teams shipping fast with AI-generated code.
