# Front-End Checklist

Front-End Checklist turns front-end best practices into a reviewable system of 385 rules across eleven categories, usable through a website, an MCP server for agent workflows, or directly inside its README.

Rules are ranked by a priority legend from critical, site-breaking issues down to low-urgency situational improvements, and each rule page adds an explanation, remediation guidance and verification steps. A companion project, UX Patterns for Devs, helps a developer choose the right interface pattern before using this checklist to verify the implementation.

The hosted MCP server exposes eleven tools so an agent can review pasted code or a live page, run structured rule lookups, and produce audits and remediation guidance across React, Next.js, HTML, CSS, JavaScript, accessibility, performance, SEO, security, images, privacy, internationalization and testing; a local stdio server is also available for editor integration.
