pr-agent
🚀 PR Agent: The Original Open-Source PR Reviewer. This project is not the Qodo free tier.
PR-Agent is an open-source AI-powered code review agent that autonomously analyzes pull requests and provides automated feedback. Originally developed by Qodo (formerly Codium AI) and now community-maintained, it integrates with GitHub, GitLab, Bitbucket, Azure DevOps, and Gitea to deliver fast, single-call reviews using various LLM providers including OpenAI, Anthropic Claude, Google Gemini, and others. Developers can deploy it as a GitHub Action, CLI tool, webhook, or Docker container to automatically generate PR descriptions, security findings, code improvements, and answer questions about changes.
