CodeRabbit
The broadest dedicated reviewer: GitHub, GitLab, Bitbucket, and Azure DevOps, plus CLI and IDE loops around the PR comment.
Best for
- Teams on mixed git hosts
- Orgs that want a dedicated reviewer with linters and issue trackers attached
- Open-source maintainers who want free public-repo reviews
Watch out
Per-seat pricing scales with PR authors, not with workspace. Pro’s hourly review cap is 5 per developer. Security scanning and Slack agent are billed separately. Confirm monthly vs annual toggle before quoting $24.
GitHub Copilot code review
The default if the team already pays for Copilot: no second GitHub App, no second vendor review.
Best for
- Teams standardised on GitHub Copilot
- Orgs that want review coverage on every PR without a seat for every author
Watch out
Shares credit pools with the rest of Copilot. Unlicensed-author coverage is policy-gated and bills AI Credits plus Actions minutes. Azure DevOps support is public preview. Buying a dedicated reviewer only pays if Copilot’s native review is too shallow for the repo.
