shadcn/ui

shadcn/ui is not a component library; it's a collection of reusable components that you copy and paste into your apps. Built on Radix UI and Tailwind.

When to Use

• Ownership: You want full control over the component code.
• Next.js: The de facto standard for modern Next.js apps.
• Modern: The "Vercel Aesthetic".
