Radix UI is an open-source UI component library for building high-quality, accessible web apps and design systems. It’s made up of a suite of low-level, unstyled components that can be used to create any kind of user interface.

Radix UI is designed to be:

  • Accessible: All components follow the WAI-ARIA design patterns, making them accessible to users with disabilities.
