CodeRabbit

CodeRabbit analyzes pull requests using codebase intelligence, external context from linked issues and web queries, and 40+ linters/scanners to deliver thorough reviews. It generates summaries, architectural diagrams, and actionable feedback, and allows developers to chat with the bot to create issues, trigger docstrings, or refine reviews. The tool learns from natural language feedback via 'Learnings' and supports custom YAML configuration. It targets teams that want to maintain code quality while accelerating development velocity.
