Shadcn UI
Tailwind CSS
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.

Disadvantages of Shadcn UI

- Depends on Radix primitives, understanding Radix helps.
- Bundle size can grow if you install too many components.
- You need to manage components in your codebase manually.
What is Tailwind CSS?
Tailwind CSS is a utility-first CSS framework that allows developers to design user interfaces by applying atomic utility classes directly in markup. Rather than offering prebuilt UI components, it empowers developers with building blocks to create fully customized and performance-optimized designs.
Key features of Tailwind CSS
- JIT Engine: Builds only the styles you use, resulting in small and fast CSS bundles.
- Utility-First Classes: Apply styling via single-purpose classes like p-4, text-sm, or bg-red-500.
- Design Tokens: Consistent spacing, sizing, and color scales across your design.
- Framework-Agnostic: Compatible with React, Vue, Svelte, Angular, and plain HTML.
- Plugin Ecosystem: Extend with official and community plugins for forms, typography, etc.
- Responsive Design: Built-in mobile-first breakpoints using prefixes like sm:, md: etc.
- Dark Mode Support: Easily implement dark mode using dark: variants or media strategies.
- No Custom Class Naming: Skip naming headaches now you can directly compose your layout visually with utility classes.
Advantages of Tailwind CSS
- No CSS Context Switching: All styling lives right in the markup — no need to jump between HTML and CSS.
- Framework Independence: Works with any modern frontend stack without restrictions.
- Design Control: Gives developers full control over the UI without being locked into component styling.
- Highly Customizable: Themes, spacing, fonts, and colors can be tailored to any brand or project.
- Consistent Design Language: Utility classes encourage consistency across the app.
- Great Ecosystem: Strong community support, tons of plugins, UI kits, and templates available.
- Performance Optimized: Small CSS bundles with tree-shaking and JIT mean faster load times.
Disadvantages of Tailwind CSS
- Verbose HTML: HTML/JSX can become cluttered with many class names.
- Initial Setup Time: Customizing themes and config files may be overkill for small projects.
- Steep Learning Curve: Takes time to get used to utility classes, especially for those used to traditional CSS.
- No Built-in Components: Unlike Bootstrap or Chakra UI, you need to build components from scratch.
- Harder for Designers: Designers unfamiliar with utility-first might find it harder to collaborate.
