AI review SaaS like CodeRabbit/Greptile/Bito/Sourcery, GitHub Copilot Code Review that hit GA in 2025, Cognition Devin showing up as a reviewer, the stacked-PR movement led by Graphite/Sapling/GitButler, the difference between native GitHub merge queue and Mergify/Aviator, plus other attempts like Reviewable/Reviewpad/Tab Code Review/Codium — all the way through noise vs signal in AI review, separation from security (Snyk Code/Aikido), Toss/Kakao/Mercari cases, ending with a decision guide for small teams, large monorepos, and OSS maintainers.
