Toolkit for accessible UIs
"Reakit is a component library for building accessible high level UI libraries, design systems and applications with React. It strictly follows WAI ARIA 1.1 standards, and all components come with proper attributes and keyboard interactions out of the box.
Reakit is modular, and components are lightweight – each adding only a few bytes to up to 3 kB to your bundle. It's unstyled by default to be fully customizable."
