Introduction
An open-source UI component library for building beautiful and accessible user interfaces.
HeroUI is a React component library built on Tailwind CSS v4 and React Aria Components. Every component comes with smooth animations, polished details, and built-in accessibility—ready to use, fully customizable.
Why HeroUI?
Beautiful by default — Professional look out of the box, no extra styling needed.
Accessible — Built on React Aria Components with focus management, keyboard navigation, and screen reader support.
Flexible — Each component is made of customizable parts. Change what you need, leave the rest.
Developer-friendly — Fully typed APIs, predictable patterns, and excellent autocompletion.
Maintained — We handle updates, bug fixes, and new features. Just update the package.
Lightweight — Tree-shaken. Only what you use goes into your app.
Future-proof — Built for React 19 and Tailwind v4, designed for AI-assisted development.
A Living Library, Not Copy-Paste
Copy-paste code works until it breaks. You're left maintaining outdated dependencies that stop evolving.
HeroUI is different. It's a living library that grows with you:
- Automatic updates and fixes
- New features without extra work
- Components stay current with React, Tailwind, and browsers
- Deep customization, not shallow theme tweaks
- AI-friendly APIs for code generation
HeroUI v3 is not a snapshot—it's a garden that keeps growing. 🌱

Why React Aria? We chose React Aria for accessibility at scale. We've used it since HeroUI v2, and v3 keeps familiar API conventions like isDisabled and onPress. Thanks to Devon Govett and the Adobe team.
