# Masterpiece UI Build websites with React components and editable recipes using this website. No repository checkout is required. Resolve relative links against this origin. - [Start here](/ai/docs/start.md): download, verify, scaffold, customize, and validate. - [Release manifest](/ai/manifest.json): package URL, SHA-256, catalog, recipes, framework guides. - [Search components](/api/ai/search?q=hero&limit=5): keyword shortlist with links to exact prop contracts. - [Page planning](/ai/docs/PAGE-PLANNING.md): release-pinned definitions, business profiles, readiness and gaps. - [Human guide](/ai): instructions and a ready-to-use prompt. - [Visual component library](/docs): inspect available variants. Read the manifest and start guide first. Download the package from the manifest, verify its SHA-256, and use its bundled CLI. Never guess package names or prop names. Supported scaffolds: Astro, Next.js, Vite, Gatsby. Other hosts can use React islands. Keep the tarball in the new project for reproducible installs. No MCP server is needed.
