PR Review is an AI-powered GitHub pull request reviewer built as a full web application rather than a browser-side script. Paste any public PR URL and pick from Claude, OpenAI, Gemini, and several free-tier providers to get a structured verdict you can copy or post back as a GitHub comment.
How it works
The heavy lifting happens on a Cloudflare Worker, not in the visitor’s browser:
- The worker fetches the pull request diff from the GitHub API.
- The diff is assembled into a structured review prompt.
- The prompt is sent to the selected model provider.
- The response is parsed into findings, severity, and a merge recommendation.
