What our tests found

CodeRabbit

On our seeded R1 pull request with 6 planted bugs, CodeRabbit posted a summary in 14s and a full review in about 2.5 minutes. It caught the off-by-one, null access, missing await and isEven bugs, flagged the hardcoded API key only as a trivial nitpick, and missed the SQL injection. 0 false positives. Single run.cloud trial

Pros
  • Caught 4 of 6 planted bugs with correct severity and fixes, with 0 false positives
  • Fast: summary in 14 seconds, full review in about 2.5 minutes
  • Free reviews forever on public repositories
  • The trial started with no card
Cons
  • Missed an obvious SQL injection
  • Flagged a hardcoded API key only as a trivial nitpick
  • Needed a manual seat assignment before it reviewed
  • The PR summary was vague
  • Private repos need a paid plan after the 14-day trial (about $90/mo shown for Advanced)

Who it’s for: Teams and open-source maintainers who want fast, low-noise AI reviews on every GitHub pull request.

Sourcery

On our seeded R1 pull request with 6 planted bugs, Sourcery caught all 6 with sensible severities, including the SQL injection and, through its secret scanner, the hardcoded key. It also raised a speculative SSRF warning. The review came about 2.5 minutes after we asked with '@sourcery-ai review'. Caveat: it reviewed after CodeRabbit and Greptile had already commented on the same PR. Single run.cloud trial

Pros
  • Caught all 6 planted bugs with sensible severities
  • Secret scanner flagged the hardcoded key
  • Free forever on public repositories, including security checks
  • Trial needs no card
Cons
  • Didn't auto-review an already-open PR; needed an '@sourcery-ai review' comment
  • Rewrote the PR description automatically
  • Raised a speculative SSRF warning, and its review comment appeared twice
  • Reviewed after two other bots had commented on the same PR, so its result may be flattered

Who it’s for: Open-source maintainers and small teams who want thorough AI reviews and security checks on GitHub or GitLab.
