Bolio UI is an open source library of accessible React components, built to be easy to customize and clear to learn.

What it is

A set of components, hooks and themes for React 18 and 19. Styles ship as static CSS, so there is no runtime injection and no registry to set up.

What guides it

Accessibility comes first: components follow the WAI-ARIA patterns and work with the keyboard. Every component is documented with a live example you can copy.

Open source
