Is CodeRabbit Free for Open Source? Yes - And for Private Repos Too

The short answer

Yes, CodeRabbit is free for open source - and the free tier goes further than that. It covers unlimited public and private repositories, which is unusual in this category. The limit is not how many repos you connect or whether they are public. It is how fast you can run reviews: roughly three back-to-back, then about four per hour.

If you came here as an open source maintainer worried about a public-repos-only restriction, there isn’t one to worry about. This page is the maintainer-specific answer - for the full plan-by-plan breakdown across every tier, see is CodeRabbit free.

What the free tier actually includes

	Free	Lite ($12/user/mo)	Pro ($24/user/mo)
Public + private repos	Unlimited	Unlimited	Unlimited
PR summaries	Yes	Yes	Yes
Review comments	Yes	Yes	Yes
Rate limits	~3 back-to-back, then ~4/hour	Raised	None
Auto-fix on reviews	No	No	Yes
40+ built-in linters	No	No	Yes
Custom review instructions	No	No	Yes
Jira / Linear / Slack	No	Basic integrations	Yes
Self-hosted	No	No	Enterprise only

The shape of this is worth noticing. CodeRabbit did not gate the free tier on repository visibility, which is the usual move. It gated on throughput and on review depth.

Where the rate limit actually bites

Three reviews back-to-back sounds generous until you map it onto how people work.

The re-run problem is the real one. Every push to an open pull request triggers a review. A PR that takes four pushes to get right has consumed four reviews, not one. If you are iterating on a change with the reviewer as your feedback loop - which is the whole appeal - you burn the allowance on a single pull request.

Team size multiplies it fast. The limit is per account, not per person. Two developers each opening two PRs in an afternoon is fine. Five developers on a Monday morning is not.

It bunches. Development is not evenly distributed across the day. Everyone opens their PRs before standup or before end of day, which is precisely when the throttle engages.

For a solo maintainer merging a handful of community contributions a week, none of this matters and the free tier is genuinely sufficient indefinitely. For a working team of five, expect to hit the ceiling inside the first week.

The trade-off nobody mentions

The rate limit gets all the attention, but the more consequential difference is what a free review is.

Free gives you PR summaries and review comments. Pro gives you the advanced review with auto-fix, the 40+ built-in linter layer, and custom review instructions via a .coderabbit.yaml file.

That last one matters more than it sounds. The single biggest complaint about AI reviewers is noise - a wall of suggestions nobody wants to read, which is how these tools end up switched off within a month. Custom instructions are the mechanism for telling the reviewer what to ignore, in plain English. It is the primary noise control, and it is not in the free tier.

So the free review is not a slightly slower Pro review. It is a shallower one, and the gap widens on larger pull requests where CodeRabbit’s known tendency toward verbosity has nothing tuning it down.

How this compares to the rest of the category

Free tiers in AI code review split into three shapes, and it is worth knowing which one you are being offered.

Free for public repos only. The most common. Fine for open source maintainers, useless for private work.

Free trial, then nothing. Gitar works this way for private repos - a 14-day trial, then paid - although it does give full Pro features free to OSI-licensed public repositories indefinitely, which is a strong offer for maintainers specifically.

Free on private repos too. CodeRabbit, and not many others. This is the reason it is the default recommendation for solo developers in our best AI code review tools roundup.

For open source maintainers there is a genuine choice between CodeRabbit’s free tier and Gitar’s free OSS Pro access, and it is not obvious. CodeRabbit gives you basic reviews with no time limit. Gitar gives you full Pro features including auto-applied fixes, but only on public OSI-licensed repos. If your project qualifies, Gitar’s free offer is the more capable one.

When to actually pay

Stay free if: you are a solo developer, an open source maintainer with moderate PR volume, or a team of two or three who mostly review each other’s code manually anyway and want AI as a second pass.

Move to Lite ($12) if: the only thing hurting is throughput. Lite raises the limits and changes nothing else. It is the right pick surprisingly rarely - most teams that outgrow free want the Pro features, not just more of the free ones.

Move to Pro ($24) if: the reviews are too noisy and you need custom instructions to tune them, or you want auto-fix, or the linter layer matters to you. Pro is where the product people demo actually lives.

Look at Enterprise if: you need self-hosted deployment. It is the only tier that offers it.

Bottom line

The answer to the question is yes, with a better catch than expected: free covers private repos too, and the constraint is speed rather than access.

The thing to actually plan around is the feature gap, not the rate limit. If you evaluate CodeRabbit on the free tier and conclude the reviews are noisy and shallow, you have evaluated the free review, not the product. That distinction is worth knowing before you write it off - or before you assume the free experience is what your team will get.
