Base UI Components with Fragments: Accessible Styling and Metadata at Scale

Teams often want the flexibility of headless primitives but still need a production-ready layer for styling, documentation, and implementation guidance. Fragments builds on Base UI components and adds that system layer so teams can scale without rebuilding the same patterns repeatedly.

## Why Build on Base UI Components

Headless primitives are great for flexibility, but they do not solve everything:

- consistent styling and theme tokens - usage guidance and examples - AI-readable metadata and tooling workflows

Fragments keeps the benefits of Base UI while adding the pieces most product teams need day to day.

## What Fragments Adds on Top

- [accessible React component docs](/components) with examples and props - [design tokens and theme builder](/create) - metadata compilation and validation in the [CLI](/cli) - AI integrations through [MCP Tools](/mcp)

This combination helps teams move faster without losing consistency as the system grows.

## FAQ

### Is Fragments a replacement for Base UI?

Fragments is built on Base UI primitives and adds styling, tokens, documentation, and metadata layers for design system workflows.

### Can I still customize behavior and styling deeply?

Yes. You keep the flexibility of a component system built on primitives while gaining a more opinionated workflow for consistency.
