Base UI
From the creators of Radix, Material UI, and Floating UI, Base UI is an unstyled React component library for building accessible user interfaces. Our focus is on accessibility, performance, and developer experience. Our goal is to provide a complete set of open-source UI components, with a delightful developer experience, in a sustainable way.
Features:
- Headless: Base UI components are unstyled, don’t bundle CSS, and don’t prescribe a styling solution.
- Accessible: Poor accessibility can make your application difficult to navigate for all users, not just for users with disabilities.
- Composable: Component APIs are fully open, so you have direct access to each node, you can easily add or remove parts, and you can wrap them however you prefer.
