You know how building a website can feel like a lot, especially when you’re trying to style every little thing yourself? Buttons, forms, layouts… it adds up fast. That’s where UI frameworks really save the day. They give you a bunch of premade design elements that you can just drop in and go. It’s like having a design starter pack that helps your site look clean and professional, without spending forever tweaking the details.

What is Shadcn UI?

Shadcn UI is a beautiful and modern component library built on top of Radix UI, styled with Tailwind CSS, and intended for Next.js projects. It offers accessible, production-ready components with theming, variants, and built-in dark mode support.

You install components via CLI and get full control over the code.
