About This Template

21st.dev is an open-source community registry and marketplace for shadcn/ui-based React components, serving as the npm for design engineers who want to publish, discover, and install minimal, modern, and reusable UI components. Inspired by shadcn/ui's philosophy, this platform provides a comprehensive collection of high-quality React components, blocks, and custom hooks powered by Tailwind CSS and Radix UI primitives, all installable with a single npx shadcn command. The registry emphasizes TypeScript support throughout, offers multiple live demos for each component to showcase different variations and use cases, and maintains a community-driven curation process ensuring component quality and consistency. Developers can browse components by category, search for specific functionality, preview components with interactive examples, and install them directly into their projects with full source code access for customization. Perfect for design engineers and React developers looking to accelerate UI development, 21st.dev eliminates the need to build common components from scratch by providing battle-tested, production-ready implementations that follow modern React patterns and accessibility best practices. The marketplace includes everything from form components and navigation elements to complex data visualizations and interactive widgets, making it an invaluable resource for teams building Next.js applications, design systems, and component libraries with shadcn/ui as their foundation.
