    21st Overview

    21st.dev is a community-powered UI library and design workspace that helps modern frontend teams collect inspiration, remix components on a canvas, and ship production-ready code faster. It curates the world’s freshest React/Tailwind/shadcn components from top creators and makes them immediately reusable—so you can explore, preview, and copy code directly into your project. With built-in AI-assisted iteration, 21st turns your canvas into new design variants automatically, helping you move from concept to implementation in minutes. Designed for product designers, frontend engineers, and startups moving quickly, 21st.dev emphasizes real, working UI over static mockups. Components are already coded and ready to integrate, with utilities like preview, open-in-tab, version history, and one-click copy. GitHub integration and background agents help you bring your own components into the workspace for AI context and seamless handoff to your codebase. Whether you’re building net-new surfaces, refreshing a design system, or assembling a marketing site, 21st.dev streamlines the journey from discovery to delivery.
