What our tests found

Greptile

On our seeded R1 pull request with 6 planted bugs, Greptile reviewed about 2.5 minutes after we asked with '@greptileai review'; it didn't auto-review the already-open PR. It flagged the off-by-one, SQL injection, missing await and isEven bugs with fixes. The hardcoded key appeared only in its header. It missed the null access. 0 false positives, but every finding was labelled P1. Single run.cloud trial

Pros
  • Caught 4 of 6 planted bugs including the SQL injection, with 0 false positives
  • Concrete fixes for each finding
  • Free Starter plan for one developer, plus free use for qualified OSS
Cons
  • Didn't auto-review an already-open PR; needed an '@greptileai review' comment
  • Missed a null access bug
  • Hardcoded API key mentioned only in the header, not as a finding
  • Every finding was labelled P1, so severity wasn't useful
  • Pro is $30 per seat per month after the trial

Who it’s for: Developers and teams who want codebase-aware AI reviews on GitHub pull requests.

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.
