The free plan looks generous (unlimited repos), but it only gives PR summaries, not line-by-line review — and line-by-line review is where this tool's real value is. The genuinely good deal is the Open Source plan for open-source projects, which allows up to 10 PR reviews and 25 chats per hour.

What Is This
Connects to GitHub, GitLab and other code hosts to auto-generate pull request summaries and line-by-line review comments.
Free Version Limitations
US$0 per user per month with unlimited public and private repos, but PRs get only a summary rather than line-by-line review. Rate limits: 1 PR review per developer per hour, 3 in the IDE and 3 in the CLI, up to 150 files per review, and chat Q&A is not available (source: docs.coderabbit.ai/management/plans). There is also a separate free Open Source plan for open-source projects: 1 to 10 PR reviews per hour depending on how active the project is, 1 in the IDE, 3 in the CLI, 100 to 300 files per review and 25 chats. Newly registered organisations also get a 14-day Pro Plus trial with no credit card, dropping back to Free on the renewal date once it expires or is cancelled. The rate quota resets on a rolling hourly basis, and the site does not say whether you are queued once it is used up, only that a Fair Usage Policy applies. (Verified 2026-08-09)

What Sets Us Apart
US$30/developer/month, billed monthly; US$24/month, billed annually. ⚠️ The official pricing page only shows US$24 and indicates Billed annually, while the monthly price of US$30 comes from official documentation.
Added a third tier: annual payment US$72 per developer per month, including continuous security monitoring; the monthly listed price on the official website’s plan card is not disclosed, and this site does not provide it (2026-09-05 direct read coderabbit.ai/pricing; docs.coderabbit.ai cross‑referenced)
Long-form writing and document quality are its strengths, with the paid version including the Claude Code engineering tool
FreeThe quota is calculated based on a rolling 5-hour usage window (not simply resetting at a fixed number every day), and general conversations can be used for around 10-20 times, excluding Claude Code.
AI code editors are a staple in the engineering community
FreeHobby: 2000 times of completion + 50 times of slow progress requests (confirmed on the official website on 2026-07-26, but the official website no longer lists these numbers in detail, only mentioning limited quota, and the specific numbers are now only seen in third-party community sources, keeping the record but adjusting the confidence level to medium)
The most popular AI completion tools have a hidden benefit of being free for students
FreeThe general user free tier includes 2,000 completions and 50 chats per month. Open-source maintainers and teachers can upgrade to Pro for free. The free student plan has reopened for new applications since 2026-06-17, after being suspended since 2026-04-20 for 58 days. As of 2026-07-27, the model selection for Free and Student plans has been limited to only Auto, and manual model specification is no longer available, while Pro and above plans are not affected.
A code review tool. The free plan lets you connect unlimited public and private repos, but only gives PR summaries, not line-by-line reviews. There's a separate, dedicated free plan for open-source projects.
