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; Essentials is $24/developer/month billed annually ($30 monthly), Team is $48 and Advanced is $72. Open-source repos get Team 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, Essentials is $24 per developer per month billed annually ($30 monthly), Team at $48 adds custom pre-merge checks, unit-test generation, and merge-conflict resolution, and Advanced at $72 adds security-informed prioritization and blast-radius review. Open-source and public repositories get Team 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 Team-plan 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 |
