Radix Primitives

Unstyled, accessible React primitives for building your own design system.

Radix Primitives is an open-source library of low-level, unstyled, accessible UI components (dialogs, dropdowns, popovers, tooltips, and more) for React. It handles focus management, keyboard navigation, and ARIA correctness while leaving all styling to the developer. It is notable as the accessibility foundation under shadcn/ui and many modern design systems.
