1. ShadCN: The TailwindCSS-Powered Modular UI Toolkit

What is ShadCN?

ShadCN is a relatively new UI framework that builds on TailwindCSS, one of the most popular utility-first CSS frameworks. By leveraging Tailwind’s utility classes, ShadCN provides a flexible and highly customizable set of UI components that can be easily integrated into any project. It’s an excellent choice for developers who want a balance between pre-designed elements and deep customization capabilities.
