Radix UI is an open-source React component library of accessible, unstyled UI primitives — WAI-ARIA compliant, fully customizable, and performance-optimized for production-grade design systems.
What is Radix UI?
Radix UI is a collection of low-level, unstyled React primitives for building accessible, high-quality user interfaces. Unlike opinionated component libraries, Radix UI gives you full control over styling while handling all the complex accessibility logic — keyboard navigation, focus management, ARIA attributes — out of the box.
It is the foundation used by popular design systems including shadcn/ui and Origin UI.
Key Features
- Accessible by default — Every component adheres to WAI-ARIA design patterns, ensuring inclusivity for all users including those using screen readers
- Unstyled primitives — Ship with zero styles, so you can apply any design system or CSS framework (Tailwind, CSS Modules, styled-components)
- Composable API — Fine-grained component parts (Root, Trigger, Content, etc.) that you compose to build exactly what you need
- Animated-ready — Built to work with CSS animations and libraries like Framer Motion
- TypeScript first — Full TypeScript support with accurate types
Available Components
Radix UI primitives include:
- Dialog, Drawer, Alert Dialog
- Dropdown Menu, Context Menu, Navigation Menu
- Tooltip, Popover, Hover Card
- Select, Combobox, Radio Group, Checkbox, Switch
- Accordion, Tabs, Collapsible
- Slider, Scroll Area, Separator
- Toast, Progress, Avatar, Aspect Ratio
Why Choose Radix UI?
Radix UI solves one of the hardest UI engineering problems: accessibility. Instead of building dropdown menus, dialogs, and tooltips from scratch and getting keyboard interactions wrong, Radix handles it all correctly while you focus on visual design.
It's the go-to choice for teams who want design freedom + accessibility compliance without maintaining their own accessible component logic.
