What is it?
Base UI is a library of unstyled React components for building user interfaces. The components handle behavior, accessibility and state, while you supply all of the visual styling, so they fit into any design system or CSS approach.
It comes from the team behind Radix, Floating UI and Material UI, and is aimed at developers who want accessible interactive elements without adopting a prebuilt visual theme. Documentation, a quick start guide and release notes are hosted at base-ui.com.
The project is written in TypeScript and distributed under the MIT license. Its repository includes a contributing guide describing how to propose fixes and build and test changes.
