CodeRabbit
An AI reviewer that comments on every PR and gets less annoying as you correct it.
What is CodeRabbit?
CodeRabbit reviews every pull request automatically and posts inline comments, a TL;DR summary and architectural diagrams of what changed. It works on GitHub, GitLab, Azure DevOps and Bitbucket, and the team behind it claims 75M+ issues found across 6 million repos. The differentiator most users mention is the Learnings system - the bot adjusts its feedback based on what your team accepts and rejects over time.
Coding agents and AI developer tools for writing, reviewing, debugging, and shipping software.
