Problem
Developers building React web and mobile applications often struggle to balance speed of development with accessibility, consistency, and customization. Many UI libraries lock teams into rigid component designs or lack robust accessibility support, requiring significant engineering effort to adapt components to specific design systems or deliver compliant user experiences.
Solution
HeroUI provides an open-source component library for both React web and React Native applications, combining React Aria Components with Tailwind CSS v4 to deliver accessible behavior, typed APIs, and customizable composition. Teams can inspect the source, use free packages, and adapt each component to their own design systems while maintaining polished defaults. The library is fully open source, allowing developers to review its implementation and publish packages under repository terms. HeroUI also offers a comprehensive documentation suite for human developers and machine-readable resources for coding agents.
Target Audience
Primary users are frontend developers and engineering teams building React-based web or mobile applications who need accessible, customizable UI components that can be adapted to their own design systems.
