Reakit helps to build accessible rich web apps with React. It is a lower level component library for building accessible high level UI libraries, design systems and applications with React. It strictly follows WAI-ARIA 1.1 standards and provides many of the widgets described in WAI-ARIA Authoring Practices like Button, Dialog, Tab and others. It has been built with composition in mind. In fact, its own components are composed by a few other abstract ones, like Role, Tabbable and Composite.
