Spectrum UI: 250+ React Components with an MCP for AI Editors
Content is AI-assisted and may contain inaccuracies.
Spectrum UI is an open-source React component and block library of 250+ animation-ready components for SaaS dashboards, landing pages, AI apps, and admin panels. Components are copied into the project via the shadcn CLI or by hand, so the source stays editable and can be adapted to an existing design system.
The stack is React, Next.js, Tailwind CSS, Motion, and TypeScript on top of shadcn/ui, and each documentation page lists the source and dependencies. An MCP server is also provided, letting editors such as Cursor or Claude add components on request.
