In the month of Sep '26, CodeRabbit delivered over 1million code reviews in open-source repos! Some interesting trends we noticed:

- The top repos by volume are newer AI/agent tooling: stablyai/orca (5.6k reviews), pingdotgg/t3code (3.9k), manaflow-ai/cmux (3.5k).

- Some established projects show up in the top 10 too: bun, vllm, pnpm, mise.

- Installed on 300k+ public repos. It's free for anyone working on public repos.

On the money side: in August we committed $10M+ (in cash and product subscription value) to open source over 12 months. About $1.3M has been counted toward it so far, per our public tracker (coderabbit.ai/oss)and we look forward to continued investment in the OSS community.

One caveat: the count includes re-reviews of the same PR, so these are review runs, not unique PRs.
