CodeRabbit
CodeRabbit is an AI code review tool that comments on pull requests, explains changes and learns team conventions, with IDE, CLI and security scanning options.
About this tool
CodeRabbit reviews code changes automatically. When a pull request opens, it posts a summary of what changed, line-level comments with suggested fixes, and checks against the repository’s templates and conventions. Developers can reply to its comments, and it records learnings, such as how a codebase maps errors to HTTP responses, to apply in later reviews.
The company argues that review, not writing code, is now the bottleneck as coding agents produce larger pull requests. Reviews run in the Git platform, in the IDE, in a CLI and inside agent loops. Higher tiers add impact analysis of affected components, architecture-level review, continuous security monitoring with exploitability grading, and a Slack assistant for engineering questions.
What you can do
Pull request reviews
Summaries and line comments with suggested patches appear automatically when a PR is opened or updated.
Learned conventions
Feedback from developers becomes stored learnings that shape future reviews of the same repository.
Reviews beyond the PR
The same review engine runs in the IDE, from a CLI and inside coding-agent workflows.
Security analysis
Higher tiers scan repositories for vulnerabilities and grade findings by severity and reachability.
Who is it for?
- A small team gets a first-pass review on every PR before a human reviewer looks at it.
- A platform team checks large agent-generated PRs for risky changes to shared components.
- An open-source maintainer triages contributions with automated summaries.
Before you choose
Plans include a number of reviews per developer per hour, so very busy teams should check the rate limits and overage options.
AI reviewers can miss context or flag false positives; keep human approval for merges, especially on security-sensitive code.
Frequently asked questions
Is CodeRabbit free for open source?
Yes. CodeRabbit offers a free plan for open-source projects and explains how to apply in its pricing FAQ.
Which platforms does CodeRabbit support?
It reviews pull requests on Git platforms and also runs in the IDE, from a command-line tool and within coding-agent loops.
Does CodeRabbit replace human code review?
No. It provides an automated first pass and context, but teams should still have people approve changes before merging.
