Testing & code review
Catch what the AI got wrong.
Picks changed this week: none. These picks were first published on 2026-10-15.
Why it wins: AI pull-request reviews on GitHub/GitLab.
Pick something else if you want tests rather than reviews (Playwright), codebase-wide review context (Greptile), or done-for-you QA (QA Wolf).

Every pricing, open-source and platform fact was checked by hand on the tool's own pricing page, docs or official GitHub repo (license file). Click a fact to open its source. Open source means an OSI-approved license in the official repo; source-available licenses such as FSL are labeled as such. Anything we couldn't confirm is marked unverified, not guessed.
