Radix UI

Radix UI provides the accessible foundations that shadcn/ui and countless design systems build upon. These are unstyled primitives that handle keyboard navigation, screen readers, and focus management so you don't have to.

Key Features:

• Accessibility Built-in - WAI-ARIA compliant by default
• Unstyled - Bring your own design system
• Composable - Build complex components from primitives
• TypeScript - Full type safety

Why Radix:

• Accessible by Default - Don't reinvent a11y wheel
• No Style Opinions - Pure functionality
• Production Proven - Powers major design systems
• Incremental Adoption - Use only what you need

Radix primitives:

• Dialogs - Modals with focus trapping
• Dropdowns - Menus with keyboard navigation
• Tooltips - Accessible hover information
• Tabs - Tab interfaces with ARIA
• And 20+ more - Complete primitive library

Radix is for teams building custom design systems who don't want to solve accessibility from scratch. It's the foundation layer—add your styles and you have a fully accessible component library.
