Unstyled UI components for building accessible user interfaces

From the creators of Radix, Floating UI, and Material UI, Base UI is a comprehensive UI component library for building accessible user interfaces with React.

Each Base UI component is meticulously designed for composability, consistency, and craft. The library's architecture prioritizes flexibility—without imposing visual opinions—helping teams craft distinctive interfaces that are fundamentally accessible and reliable.

Collectively, we've been building component libraries for multiple decades. We've learned what works, what lasts, and what doesn't. And we really, really sweat the details.

Base UI is built to last. It is designed with care and maintained with intent. Our mission is to provide a future-proof foundation for professional interface design on the Web.
