CodeRabbit
AI code-review bot that posts line-by-line PR feedback, summaries, and fixes on GitHub, GitLab, Azure DevOps, and Bitbucket, plus a free IDE and CLI reviewer
CodeRabbit is an AI code-review bot that posts line-by-line feedback, PR summaries, and one-click fixes across GitHub, GitLab, Azure DevOps, and Bitbucket. A free tier covers public and private repos with rate-limited reviews; Pro is $24/developer/month billed annually ($30 monthly) and Pro+ is $48. Open-source repos get Pro+ features free. It reviews code rather than writing features, so it complements coding tools like Claude.
What is CodeRabbit?
CodeRabbit is an AI bot that reviews pull requests. When a PR opens, it reads the diff in context, posts line-by-line comments flagging bugs and issues, and writes a summary with a TL;DR of the changes and diagrams for larger diffs. You can reply to its comments in the thread to ask questions or push back, and for straightforward problems it offers Fix-with-AI suggestions that commit in one click. It works across GitHub, GitLab, Azure DevOps, and Bitbucket, and a separate free IDE extension and CLI bring the same review to VS Code, Cursor, and Windsurf before you ever push.
Importantly, CodeRabbit reviews code rather than writing features — it is a reviewer, not a coding agent, so it sits alongside tools like Claude rather than replacing them. Pricing is per developer: a free tier covers public and private repos with rate-limited reviews, Pro is $24 per developer per month billed annually ($30 monthly), and Pro+ at $48 adds custom pre-merge checks, unit-test generation, and merge-conflict resolution. Open-source and public repositories get Pro+ features free, and API access plus self-hosting are reserved for the custom-priced Enterprise tier.
Who is it for?
CodeRabbit fits teams that want a consistent first-pass review on every change without adding load to senior engineers. It is most valuable where review is a bottleneck or where coverage is uneven across a codebase.
- Engineering teams that want every PR triaged for bugs and style before a human reviewer looks, shortening review cycles.
- Open-source maintainers who get full Pro+ features free and can keep quality high on community contributions.
- Solo developers and small teams using the free IDE extension and CLI to catch issues locally before pushing.
- Compliance-conscious orgs that need self-hosting, SSO, RBAC, and audit logging via the Enterprise plan.

Pros and cons
| Pros | Cons |

| Free tier and free IDE/CLI extension let individual developers use it at no cost | Automated reviewers can surface noise and nitpick comments that still need human triage |
| Broad platform coverage: GitHub, GitLab, Azure DevOps, Bitbucket, and major IDEs | API access and self-hosting are gated behind custom-priced Enterprise, not Pro or Pro+ |
