## Why HeroUI? HeroUI (previously NextUI) is a production-ready React component library that combines the accessibility rigor of [React Aria](https://react-spectrum.adobe.com/react-aria/) with the utility-first styling of [Tailwind CSS v4](https://tailwindcss.com/). It ships a clean compound component API (`Card.Header`, `Card.Content`, `Select.Item`, …), requires no `` 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 | Package | Description | |---|---| | [`@heroui/react`](https://www.npmjs.com/package/@heroui/react) | Full component bundle | | [`@heroui/styles`](https://www.npmjs.com/package/@heroui/styles) | Styles / theme only | | Individual packages | e.g. `@heroui/button`, `@heroui/modal` — tree-shakeable per-component imports | ## Getting Started Visit [heroui.com/docs/react/getting-started/quick-start](https://heroui.com/docs/react/getting-started/quick-start) to get started with HeroUI. ```bash npm install @heroui/react ``` ## 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](https://heroui.com/llms.txt) — structured context for LLMs about every component | | **Agent Skills** | Run `npx heroui-cli agents-md` to install skills for Cursor, Claude Code, and more | 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 | ## Documentation - **Latest (v3)**: [heroui.com](https://heroui.com) - **v2**: [v2.heroui.com](https://v2.heroui.com) ## Storybook Visit [storybook-v3.heroui.com](https://storybook-v3.heroui.com/) to view the storybook for all components. ## Roadmap Visit [herouiv3.featurebase.app/roadmap](https://herouiv3.featurebase.app/roadmap) to view the roadmap for HeroUI v3. ## Figma Visit the [HeroUI Figma Kit (v3)](https://www.figma.com/community/file/1546526812159103429/heroui-figma-kit-v3) to view the design kit. ## Community We're excited to see the community adopt HeroUI, raise issues, and provide feedback.
