👉Get Started Now

PR-Agent is an open-source, AI-powered code review agent and a community-maintained legacy project of Qodo. It is distinct from Qodo’s primary AI code review offering, which provides a feature-rich, context-aware experience. Qodo now offers a free tier that integrates seamlessly with GitHub, GitLab, Bitbucket, and Azure DevOps for high-quality automated reviews.

Big News for PR-Agent

PR-Agent has a new home!

After years of building this tool alongside the community, Qodo has donated PR-Agent to the open-source community - and we couldn't be more excited about what comes next.

The project now lives in the PR-Agent org on GitHub, is fully community-owned, and is open for contributions and additional maintainers.

What else changed:

• Docs moved to - www.pr-agent.ai
• Qodo Merge (Qodo 1.0), the hosted URL, which was the enterprise version of PR-Agent, has been rebranded and evolved into Qodo (Qodo 2.0), a full AI code review platform.
