Radix UI is a library of unstyled, accessible React primitives — the low-level building blocks for dialogs, dropdowns, popovers, sliders, tabs, and more. It handles the hard parts that are easy to get wrong: keyboard navigation, focus management, screen reader support, and positioning, while leaving all visual styling to you.

  • Keyboard navigation and focus management built in
  • Screen reader support out of the box
  • Dialogs, dropdowns, popovers, sliders, and more
  • Works with any styling approach

How it works

Because Radix components ship without styles, they fit any design system. You bring your own CSS or Tailwind classes, and Radix makes sure the behaviour is correct and accessible. It is the foundation underneath shadcn/ui and many other modern component libraries, which is a good sign of its quality.

Radix UI is free and open source under the MIT licence. It is not a plug-and-play UI kit — it is a toolkit for teams that care about accessibility and want full visual control. For design-system builders, it saves months of work on interaction details.
