OpenReview

OpenReview is an open-source, self-hosted AI-powered code review system designed to automate and enhance the pull request review process using advanced language models. Built by Vercel Labs, it integrates directly with GitHub workflows, allowing developers to trigger intelligent code reviews by simply mentioning a bot in a pull request. The system operates in a sandboxed environment with access to the repository, enabling it to run linters, tests, and formatting tools as part of its review process. It provides detailed, line-by-line feedback and can suggest or even apply fixes directly to the codebase. OpenReview is designed for extensibility, supporting custom review skills that can be tailored to specific development needs or coding standards. Its architecture leverages Vercel’s infrastructure for scalable and reliable execution, ensuring that reviews can be resumed or retried if interrupted.
