HeroUI v3 announced
HeroUI released v3 — a major rewrite with 75+ React components, 37+ React Native components, Tailwind CSS v4 support, performance‑focused CSS animations, and new AI features like an MCP Server for UI workflows. The package is pitched as a fast way to build accessible, modern UI portfolios. (x.com)
HeroUI v3 was formally published in March 2026 as the new major v3 release on the project site. (heroui.com/docs/react/releases/v3-0-0) The project's main GitHub repository labels v3 as a beta branch and states maintainers are working to move it toward a stable release while keeping the v2 branch available for production users. (github.com) HeroUI published an MCP Server to let AI assistants access component documentation programmatically; the React MCP package is published as @heroui/react-mcp on npm and the MCP docs note stdio transport support. (heroui.com/docs/react/getting-started/mcp-server ) (npmjs.com) The heroui-mcp monorepo on GitHub contains the MCP server source and shows active development with recent merges and commits, and the README documents MCP usage for AI-assisted workflows. (github.com) HeroUI is running a Pro pre-sale that lists premium components, templates, and advanced MCP/Skills tooling at heroui.pro with pre-sale pricing displayed on the v3 site. (v3.heroui.com) A migration helper (heroui-migration-mcp) has been published to automate common v2→v3 changes, and the v3 alpha was announced to the community via a GitHub discussion on Oct 21, 2025.
