HeroUI (previously NextUI) is a production-ready React component library that combines the accessibility rigor of React Aria with the utility-first styling of Tailwind CSS v4. It ships a clean compound component API (Card.Header, Card.Content, Select.Item, …), requires no <Provider> wrapper, and works out of the box with React 19 and Next.js.
- Accessible by default — Built on React Aria for WCAG-compliant keyboard, focus, and screen-reader behavior
- Tailwind CSS v4 — Modern engine, no CSS-in-JS runtime, smaller output, faster builds
- Compound components — Composable API (
Card.Header,Card.Content) instead of deeply nested props - Zero boilerplate — No Provider wrapper needed (unlike Chakra, MUI)
- AI-native — MCP server,
llms.txt, and agent skills so AI assistants understand your components - Battle-tested — Previously known as NextUI, trusted by thousands of production apps

- Any React / Next.js project that values design quality and accessibility
HeroUI is built for the AI-assisted development workflow.
| Tool | What it does |
|---|---|
MCP Server (@heroui/react-mcp) |
Components that understand your theme — install the server in Cursor, Claude Code, Windsurf, or any MCP-compatible editor |
| llms.txt | Available at heroui.com/llms.txt — structured context for LLMs about every component |
| AGENTS.md | Run npx heroui-cli@latest agents-md --react to download React v3 documentation into your project |
| Agent Skills | Run npx skills add heroui-inc/heroui to install skills for supported coding agents |
Works with Cursor, Claude Code, Windsurf, GitHub Copilot, and any tool that supports MCP or llms.txt.
| Library | How HeroUI differs |
|---|---|
| shadcn/ui | HeroUI is batteries-included with a consistent design system; shadcn is copy-paste-customize |
| MUI | HeroUI is lighter, Tailwind-native, no CSS-in-JS runtime overhead |
| Chakra UI | HeroUI uses React Aria (stronger a11y primitives) and Tailwind v4 (better perf) |
| Mantine | HeroUI has AI tooling (MCP, llms.txt), Tailwind-first styling |
