Compare Tools

Radix UI is an open-source library of unstyled, accessible UI primitives for React. It provides the complex logic for difficult components—like Dropdowns, Dialogs, Tooltips, and Accordions—but applies zero CSS styles to them. This "Headless" approach means developers get full WAI-ARIA accessibility compliance and keyboard navigation logic out of the box, but have 100% freedom to style the components to match their brand using any CSS tool (like Tailwind or Stitches). For design system teams, Radix UI is the perfect foundation. It saves months of engineering time that would be spent re-inventing the wheel on accessibility behaviors, ensuring that your custom design system is robust, inclusive, and usable by people with disabilities.
