- Sign in at coderabbit.ai with GitHub (or GitLab/Bitbucket/Azure DevOps) and install the app on a test repository first, not your whole organization.
- Open a small PR to see a review: a summary of changes plus line-level comments.
- Add a .coderabbit.yaml file to set review tone, paths to ignore (generated code, lockfiles, vendored folders) and project-specific instructions such as your conventions.
- Reply to its comments in the PR thread to ask why, request a fix, or tell it a suggestion is wrong; it uses that feedback for future reviews.
- Keep a human approval rule in branch protection; treat the AI as a first pass that catches issues before your reviewers look.
Why CodeRabbit
CodeRabbit is a dedicated review tool: it summarizes each PR, leaves line-level comments, takes per-repo configuration and lets you discuss its comments in the thread. A focused, configurable reviewer tends to be more useful on every PR than a general assistant asked to review occasionally.
When to choose GitHub Copilot instead
Choose GitHub Copilot if your team already pays for Copilot and lives on GitHub. Its code review is built into the PR reviewer menu and needs no extra vendor, which is often enough for smaller teams.
