HeroUI v3 Lands as a Ground-Up Rewrite for React and React Native, Built on Tailwind CSS v4

HeroUI v3, a ground-up rewrite of the React component library formerly known as NextUI, has been released with over 75 web components and a new React Native library of 37 components. Built on React Aria Components and Tailwind CSS v4, the library features AI-assisted development tools and a Figma Kit, but some users report missing features from v2. The open-source project, backed by Y Combinator, now records around 341,000 weekly npm downloads.

HeroUI https://heroui.com/ , the React component library formerly known as NextUI, has released HeroUI v3 https://heroui.com/docs/react/releases/v3-0-0 , a ground-up rewrite that the team frames as one design system for web and native. The March 2026 release ships more than 75 web components, 21 of them new, alongside a brand-new React Native library built from scratch with 37 components. HeroUI v3 is built on React Aria Components https://react-spectrum.adobe.com/react-aria/ for accessibility and Tailwind CSS v4 https://tailwindcss.com/ for styling, exposing CSS variables, OKLCH colours and BEM modifiers for customisation. Every animation has moved to CSS with no JavaScript runtime, and the library adopts a compound component API that drops the old provider wrapper and works out of the box with React 19 and Next.js. The rewrite also leans heavily into AI-assisted development, shipping an MCP Server https://heroui.com/docs/react/getting-started/mcp-server , Agent Skills and an llms.txt file so coding assistants can read component docs directly, plus a Figma Kit v3 https://www.figma.com/community/file/1546526812159103429/heroui-figma-kit-v3 with 1:1 component parity. On npm https://www.npmjs.com/package/@heroui/react the core @heroui/react package now records around 341,000 weekly downloads, the separate heroui-native package adds roughly 11,000 a week, and the GitHub repository https://github.com/heroui-inc/heroui sits near 27,700 stars. Several point releases have landed since 3.0. v3.0.3 https://heroui.com/docs/react/releases/v3-0-3 upgraded React Aria Components to 1.17.0 and dropped around 90 percent of its transitive dependencies for faster installs, while adding a Typography component. v3.1.0 https://heroui.com/en/docs/react/releases/v3-1-0 in late May added Chinese documentation, expanded soft colour tokens, a shared themeable scrollbar system and SSR fixes for useTheme , and v3.2.0 https://github.com/heroui-inc/heroui/releases arrived on 16 June 2026 as the current line, with monthly minor releases now the stated cadence. A long-time NextUI and v2 user writing on Reddit https://www.reddit.com/r/reactjs/comments/1u87zmy/heroui v3 is it just me/ praised the themes page and documentation but lamented that input label animations, prebaked units and autocomplete were "all gone" in v3: I have just started a new project using v3. The themes page is pretty and the documentation is bang on as usual, but I keep finding things missing which I loved in v2... The choice of animations for labels on inputs, the ability to have units prebaked into them, the autocomplete... all gone. On GitHub https://github.com/heroui-inc/heroui/discussions/6080 , developers questioned the roadmap and missing pieces such as Navbar, with one noting "there's some lack of transparency of the project timeline for sure." Teams moving from v2 should plan carefully, because v2 and v3 cannot coexist in the same project. The official migration guide https://heroui.com/docs/react/migration offers both a full migration https://heroui.com/docs/react/migration/full-migration and an incremental migration https://heroui.com/docs/react/migration/incremental-migration path, supported by a dedicated migration MCP server, and some components such as Image have been removed entirely in favour of native elements.
