PR-Agent
The original open-source AI pull-request reviewer, now community-maintained.
PR-Agent is an open-source AI code-review agent that runs on pull requests via slash commands such as /describe, /review, /improve and /ask, each using a single LLM call. It works with GitHub, GitLab, Bitbucket, Azure DevOps and Gitea, deploys as a GitHub Action, webhook or Docker image, and reaches OpenAI, Anthropic, Gemini, DeepSeek and other models through LiteLLM. It is a community-maintained legacy project of Qodo (earlier images were published under the codiumai namespace), distinct from Qodo's commercial review product, with Qodo as a sponsor.
