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.
