CodeRabbit is an AI code review tool that posts on every pull request: a plain-language summary with sequence diagrams, plus line-by-line feedback flagging bugs, security issues, and performance problems with one-click fix suggestions. It runs 30+ static analysis and SAST tools (ESLint, Ruff, golangci-lint, Clippy, TruffleHog, Trivy, and more) in sandboxes, and works across GitHub, GitLab, Azure DevOps, and Bitbucket. It is aimed at engineering teams that want faster, more consistent PR reviews without replacing human reviewers.
