# OpenReview
An open-source, self-hosted AI code review bot. Deploy to Vercel, connect a GitHub App, and get on-demand PR reviews powered by Claude.
> **Beta**: OpenReview is currently in beta. It was built as an internal project to help the Vercel team test their technologies together. Expect rough edges and breaking changes.

## Features
- **On-demand reviews** — Mention `@openreview` in any PR comment to trigger a review. Powered by [Chat SDK](https://chat-sdk.dev)
- **Sandboxed execution** — Runs in an isolated [Vercel Sandbox](https://vercel.com/docs/sandbox) with full repo access, including the ability to run linters, formatters, and tests
- **Inline suggestions** — Posts line-level comments with GitHub suggestion blocks for one-click fixes
- **Code changes** — Can directly fix formatting, lint errors, and simple bugs, then commit and push to your PR branch
- **Reactions** — React with 👍 or ❤️ to approve suggestions, or 👎 or 😕 to skip
- **Durable workflows** — Built on [Vercel Workflow](https://vercel.com/docs/workflow) for reliable, resumable execution
- **Extensible skills** — Ships with built-in review [skills](https://skills.sh) and supports custom skills via `.agents/skills/`
- **Powered by Claude** — Uses Claude Sonnet 4.6 via the [AI SDK](https://sdk.vercel.ai) for high-quality code analysis
- **Simple route handler** — Easily define route handlers using [Next.js Route Handlers](https://nextjs.org/docs/app/building-your-application/routing/route-handlers) for custom API endpoints and webhooks

```
1. Mention `@openreview` in a PR comment (optionally with specific instructions)
2. OpenReview spins up a sandboxed environment and clones the repo on the PR branch
3. A Claude-powered agent reviews the diff, explores the codebase, and runs project tooling
4. The agent posts its findings as PR comments with inline suggestions
5. If changes are made (formatting fixes, lint fixes, etc.), they're committed and pushed to the branch
6. The sandbox is cleaned up
