AI reviewer that comments on GitHub and GitLab pull requests, triages them by risk and flags security issues
CodeRabbit installs as a GitHub or GitLab app and reviews every pull request automatically, leaving line-level comments, one-click fixes and a risk-ranked triage queue, with extra reviews available in the IDE and CLI. It is aimed at teams whose PR volume has ballooned because coding agents now write much of the diff. Public open-source repositories get reviews at no charge; commercial teams pay per seat, starting at $24 per user/month on the Pro plan with a 14-day trial, and a separate Security product watches for vulnerabilities.
Pro is $24 and Pro Plus $48 per user/month on annual billing, both with a 14-day trial and hourly caps (5 and 10 PR reviews per developer per hour). Add-ons include CodeRabbit Security at $40 per user/month and a $0.50-per-minute Slack agent; public open-source repos are reviewed free.
Use tool ↗The most sensible fit is a team merging a steady stream of agent-generated PRs that no human can fully read. The catch is the fair-usage meter: even paid seats are capped at a handful of PR reviews per developer per hour, and the bot's default verbosity takes tuning.
Watch out: Budget for the caps: 5 PR reviews per developer per hour on Pro can pinch during release crunches, and the unlimited option is a usage-billed add-on.
