SmoothUI is a modern UI component library designed for building visually rich and interactive web applications using React. It combines Tailwind CSS for styling and animation libraries like Motion (Framer Motion) and GSAP to deliver smooth, performant animations out of the box.

The library provides a collection of reusable components and UI blocks—such as buttons, modals, accordions, hero sections, pricing layouts, and dashboards—that can be easily integrated into projects. Developers can either install components using tools like the shadcn CLI or copy them directly into their codebase for full customization.

SmoothUI is built with modern React practices including TypeScript support, server components, and hooks, ensuring both performance and developer productivity. It also emphasizes accessibility, responsiveness, and theming, with built-in support for dark mode and customizable design tokens.

A notable aspect of SmoothUI is its focus on AI-assisted development, offering machine-readable component catalogs and APIs that allow AI agents to discover, install, and use components programmatically.

Overall, SmoothUI helps developers quickly build polished, animation-rich interfaces without needing to design or implement complex UI interactions from scratch.
