CodeRabbit

What is CodeRabbit?

CodeRabbit is an AI code-review platform that works with pull requests and also provides review experiences in IDEs and the command line. It analyzes code changes, produces a summary and walkthrough, flags potential defects, and suggests line-level fixes. Developers keep responsibility for the final review and can apply simple fixes as commits or use an AI-assisted fix for more involved issues.

The review agent combines codebase intelligence with project guidelines and external context. It can use linked Jira or Linear issues, MCP servers, web information, and more than 40 linters and security scanners. Teams can configure instructions by path or syntax tree, define custom checks in natural language, and teach future reviews through feedback.

Core Features

• Pull-request review: Analyzes diffs and posts contextual feedback before code is merged.
• Change summaries: Produces a concise summary, file walkthrough, and architecture diagram for a change.
• Bug and security detection: Uses codebase context, linters, and scanners to identify defects and risks.
• Suggested fixes: Offers one-click commits for simple corrections and AI-assisted changes for harder issues.
• Custom review rules: Applies coding guidelines, path-specific instructions, and natural-language pre-merge checks.
• Learning from feedback: Incorporates reviewer replies into future review behavior.

Use Cases

• Pull-request triage: Developers can see the purpose, affected areas, and likely risks of a change before detailed review.
• Defect detection: Engineering teams can identify edge cases, null handling, static-analysis findings, and security issues.
• AI-generated code governance: Teams can add a consistent review layer to code created quickly by coding agents.
• Test and documentation completion: Developers can generate missing unit tests or docstrings during finishing checks.
• Local review: Engineers can review work in an IDE or CLI before opening or updating a pull request.
