OpenReview is a self-hosted GitHub App developed by Vercel Labs designed to act as an automated assistant for pull request reviews. Triggered by mentioning `@openreview` in a PR comment, the tool uses Claude Sonnet 4.6 via the AI SDK to spin up isolated sandboxed environments where it runs actual project tooling ''such as linters, formatters, and tests'' to provide actionable suggestions or direct code fixes. It is deeply integrated with Vercel's infrastructure, utilizing Vercel Workflows for orchestration and Vercel Sandboxes for execution.
