Fragments is the first AI-native design system SDK.

Every team using AI to write code hits the same wall: AI doesn't know your design system. Cursor, Claude Code, and Copilot generate UI from scratch every time. Wrong components, wrong tokens, wrong patterns. You fix it manually, or worse, ship it.

Fragments fixes this. It ships 60+ production-ready React components, a seed-based token system, and MCP tools that make AI agents build UI with your components, tokens, and patterns. No generic code that drifts from your design system.

What you get:
  - 60+ accessible, themeable React components built on headless primitives
  - Seed-based theming
  - MCP tools so AI assistants query your design system in real time
  - CLI with built-in accessibility auditing, local preview, and CI integration
  - Zero-config alternative to Storybook — docs, a11y, and AI context generated from metadata

Free and open source. MIT-licensed components. Built for developers who want AI that writes code like their senior engineers.
