Why HeroUI?

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

Packages

Who Is This For?

HeroUI is a good fit if you are building:

SaaS applications — forms, tables, overlays, and notifications out of the box
Dashboards & admin panels — data-dense layouts with consistent design tokens
E-commerce storefronts — performant, accessible, SEO-friendly components
Marketing sites & landing pages — polished UI without a heavyweight runtime
Any React / Next.js project that values design quality and accessibility

AI-Powered Development

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.

Compared To

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
