Introduction

Mizu is a Frutiger Aero design system for Svelte. Glossy, glassy, gorgeously rounded components that bring back the optimism of early-2000s UI, built honestly for Svelte 5 and Tailwind v4.

Why Frutiger Aero

The aesthetic of clear skies, water droplets, and wet glass had a confidence we lost somewhere in the flat years. Mizu (水, "water") leans all the way in: frosted glass, a real top sheen, layered light, bright aqua, and generous rounding, applied with restraint so it feels polished instead of busy.

Principles

• Physically honest. Gloss, glass, and glow come from real CSS, never baked-in screenshots.
• Accessible underneath. Interactive components wrap bits-ui primitives, so keyboard and screen-reader behavior is handled.
• Yours to own. Components are copied into your project as source. No black-box dependency, no version lock.
• Tokens all the way down. One theme file drives every surface, in a sunlit light mode and a deep-water dark mode.

How it ships

Mizu is distributed as a shadcn-svelte-compatible registry. Real developers install components with tooling they already know; AI agents get clean per-component JSON; and every component page here shows the full source to copy by hand. 50 components are ready today.
