OSS testimonials
How CodeRabbit helped these projects.
“We’re using CodeRabbit all over NVIDIA.”
Jensen Huang, Founder & CEO
“Before CodeRabbit, quality depended on who reviewed your PR. Now, the bar is the same for everyone.”
Abhi Aiyer, CTO
“CodeRabbit has proven invaluable in highlighting inconsistencies like missing null checks or mismatched value ranges. That... prevented numerous potential issues.”
David Deal, Senior Director of Eng
“I love how deeply it analyzes code… It spots potential errors more often than other tools.”
Gabriel Almeida, Technical founder

Frequently Asked Questions
- The repo is public. That’s the whole bar CodeRabbit uses: if anyone can read your repository’s code, it’s open source, and triage, reviews, change stack, and security are all free.
- Install CodeRabbit from the GitHub or GitLab marketplace and turn it on for your public repositories. Reviews start on the next pull request — two clicks, no credit card, no sales call.
- No. There’s no application or approval queue: every public repository gets CodeRabbit Review free the moment you install it. Cash sponsorships are separate. We fund maintainers proactively through GitHub Sponsors, direct invoices, and Open Collective.
- The live tracker on this page reports the open source pull requests CodeRabbit reviews and the usage costs we cover using a public data feed with sources, dates, and methodology. The more code a reviewer sees, the sharper its context gets, and open source is where that learning compounds.
- The maintainers on this page say it best, including pnpm, Nuxt, Testcontainers, and the Linux Foundation. CodeRabbit reviews every pull request with whole-codebase context, verifies findings in sandboxes, learns your team’s conventions, and catches AI slop before it reaches your queue. And we show our work: we publish open eval blogs, and the feedback from reviewing public open source keeps making reviews better.
- AI code reviews are free on every public repository, and the OSS offer includes slop detection, triage, Change Stack, and Security reviews on pull requests by default. Discord support is included for large open source projects.
- Yes. Beyond free product access, we’ve paid more than $1.2M in cash to maintainers and projects through GitHub Sponsors, direct invoices, and Open Collective, with the total tracked live on this page.
- CodeRabbit supports GitHub, GitLab, Bitbucket, and Azure DevOps, with reviews also available in your CLI and IDE.
- At cost, not list price. It counts what it actually costs us to run CodeRabbit on public repositories, plus cash sponsorships to maintainers, from the Series C announcement onward. The live tracker on this page reports progress from a public JSON feed anyone can inspect.
