About HeroUI
Overview
HeroUI is an open-source component library for React web and React Native mobile applications. The web library combines React Aria Components with Tailwind CSS v4 to provide accessible behavior, typed APIs, customizable composition, and polished defaults.
It is a Y Combinator S24 company founded by Junior Garcia. Teams can inspect the source, use the free packages, and adapt each component to their own design system.
