PR-Agent, originally created by CodiumAI (now rebranded as Qodo), is an open-source AI-powered tool that integrates directly into GitHub, GitLab, and Bitbucket pull requests. Developers trigger it via slash commands in PR comments to auto-generate PR descriptions, perform code reviews with inline suggestions, propose specific code improvements, answer questions about the PR, and update changelogs. As of 2026 the open-source project is community-maintained under The-PR-Agent GitHub organization under Apache 2.0. Key features: - /describe: auto-generates PR title and description - /review: AI code review with categorized feedback and improvement suggestions - /improve: generates committable code improvement patches - /ask: Q&A about specific code in the PR - /update_changelog: automated changelog updates - Supports OpenAI, Anthropic Claude, Google Gemini, and BYOK configurations
Open-source (Apache 2.0): free, user pays own LLM API costs. Qodo commercial product: Developer free; Teams $30/user/month; Enterprise custom.
