# uSpec (Design systems)

> uSpec is a free, open-source design system. Generate design system documentation for your UI components, directly from your AI agent. It has 244 GitHub stars and is released under the MIT license. A live demo is linked from this page.

Generate design system documentation for your UI components, directly from your AI agent. Describe a component to your agent. uSpec captures it with the uSpec Extract Figma plugin, compiles a canonical component contract (.json) plus a portable implementation guide (.md), then renders sections of that specification back into Figma as annotation frames. Works with Figma Console MCP or the native Figma MCP, inside Cursor, Claude Code, or Codex.
