About this project

Front-End Checklist is an open-source front-end quality system designed for both humans and AI agents. It transforms front-end best practices into a practical review workflow accessible via a website, an MCP-compatible server, or directly in the README. Key capabilities include: - 385 English rules across 11 active categories: HTML, CSS, JavaScript, Performance, Accessibility, SEO, Security, Images, Testing, Privacy, and Internationalization. - 11 MCP tools exposed by a hosted server for agent-driven code review, audits, and remediation workflows. - Rule pages with explanations, remediation guidance, and verification steps. - Priority levels (Critical, High, Medium, Low) to help triage issues by impact. Usage options: - Browse and filter rules on frontendchecklist.io. - Connect an MCP-capable agent to the public endpoint for frontend code review, structured rule lookup, and audits of pasted code or live public URLs. - Install reusable audit workflows as skills in compatible tools. The MCP server supports reviewing React, Next.js, HTML, CSS, JavaScript, and more, covering accessibility, performance, SEO, security, images, privacy, i18n, and testing. Example agent workflows include reviewing pasted components, auditing live URLs, fetching specific rules with remediation guidance, and searching rules by keyword, category, or priority. A companion project, UX Patterns for Devs, helps developers choose appropriate UI patterns before using Front-End Checklist to verify implementation quality.
