Bottom line: CodeRabbit is free in a specific, useful way — and the headline version most people repeat is wrong for private code. Public open-source repositories get full AI reviews for free. On the regular Free plan for private work, pull requests get summaries only; the actual free reviews live in the IDE extension and CLI, at 3 reviews per hour each. If you maintain an open-source project, this is generous. If your code is private, treat Free as a preview and expect a paid plan for real PR review.

What is CodeRabbit?
CodeRabbit is an AI code review tool that works on pull requests across GitHub, GitLab, Bitbucket, and Azure DevOps, with additional review paths in an editor extension and a CLI so you can get feedback before you push. On paid plans it adds plain-language PR summaries and walkthroughs, chat about the changes, learnings captured from prior reviews, one-click autofixes, pre-merge checks, and newer triage, change-explanation, and security features. It is a reviewer, not a code generator — for comparison, Qodo covers code review plus test generation, while tools like Tabnine focus on completions inside the editor.
What is actually free?
There are two distinct free routes, and mixing them up is where most coverage goes wrong:
- Open source (OSS): full AI reviews on public repositories, free, with team features on public repos. Per CodeRabbit’s docs, OSS review limits are scoped per repository and vary — the plans table lists 1 PR review per hour in its rate-limit row for OSS, with 3 CLI reviews per hour and chat included.
- Free plan (including private repos): pull requests receive summaries, not full reviews. Reviews are available in the IDE extension and the CLI at 3 per developer per hour each, up to 150 files per review. Chat is not included on Free, and linked repositories are 0.
Paid plans, per the vendor’s pricing page as checked in November 2026, start at Essentials at $24 per developer per month billed annually ($30 monthly), then Team at $48 annually ($60 monthly) and Advanced at $72 annually ($90 monthly), with Enterprise by sales. New organizations get a 14-day trial of paid features. Only developers who open pull requests count as seats.
What the pricing page doesn’t make obvious
The Free plan’s PR column is blank in CodeRabbit’s own rate-limit table — on purpose. In the official plans documentation, the Free row shows no PR review allowance at all, only 3 IDE and 3 CLI reviews per hour. That is the documented gotcha: “free CodeRabbit” for a private repository means summaries on your PRs plus a small hourly allowance of local reviews, not an AI reviewer commenting on every pull request. A second detail from the same docs: for public repositories with fewer than 10 stars, reviews do not run automatically — you trigger one manually from the CodeRabbit status comment or by commenting @coderabbitai review.
Pros and cons
Pros
- Full reviews genuinely free for public open-source repositories
- Free plan still covers unlimited repositories for PR summaries
- IDE and CLI reviews (3/hour each) let private-code users test review quality free
- Works across GitHub, GitLab, Bitbucket, and Azure DevOps
- Paid pricing counts only developers who open PRs, not every seat in the org
Cons
- No full PR reviews on private repositories without a paid plan
- Free plan has no chat, no linked repositories, and no knowledge repositories
- Small public repos (under 10 stars) need reviews triggered manually
- Reviews beyond hourly paid allowances can incur per-file usage charges on paid plans
Who is CodeRabbit best for?
CodeRabbit’s free tiers are best for open-source maintainers who want a tireless first-pass reviewer on every public pull request, and for individual developers who want to sample AI review in their editor or terminal before a team commits to paying. Private teams should run the 14-day trial on real PRs rather than judging the tool by the Free plan, because the Free plan deliberately does not show the main event. If you mainly need completions rather than review, a tool like Cursor is the different-shaped alternative.

Verdict
CodeRabbit is one of the best free AI review offers for open source, and a much narrower offer for everyone else. Know which of the two free plans you are actually on, and it is a useful tool at $0. Assume the headline applies to your private repo, and you will be disappointed in the first week.
