Why ParamUI?

A modern approach to building design systems — own your code, not your dependencies.

Zero Lock-in

Copy the source into your project. No packages to update, no breaking changes from upstream.

Accessible by Default

Semantic HTML, ARIA attributes, keyboard navigation, and focus management baked in.

Tailwind CSS Native

Every component uses Tailwind utility classes. Light and dark mode, responsive — all built-in.

Live Previews

Every component has an interactive preview with demo data so you can see exactly what you're getting.

One-Click Copy

Click the copy button on any component to grab the full source. Paste and ship.

Fully Customizable

Design tokens via CSS variables. Swap colors, radii, fonts — the theme is yours to own.

Built With

Modern foundations, zero bloat.
