Shadcn/ui

Shadcn/ui outperforms #9 as the most-starred new project on GitHub in 2024, earning over 80,000 stars within its first year. Built on Radix UI and Tailwind CSS, its revolutionary "copy-paste" distribution model grants developers full ownership of each component's code, enabling infinite customization for design systems — a freedom no other library offers. This approach makes it the default component library for Next.js applications, faster than the average new UI framework to integrate and adapt. With 30% fewer dependencies than the typical rival library, Shadcn/ui streamlines development while maintaining a clean, accessible codebase.
