Front-End Checklist

Front-End Checklist is the open-source front-end quality system for humans and AI agents. It turns front-end best practices into a practical review workflow you can browse on the web, run through with MCP-compatible tools, or work through directly in this README.
Companion project: UX Patterns for Devs helps developers choose the right UI pattern before using Front-End Checklist to verify implementation quality.
[!IMPORTANT]
Use the website for browsing and filtering, the MCP server for agent workflows, and this README when you want the checklist in one place.
