A design spec
for user interfaces

Stisla is framework-agnostic by design. One spec, with a native implementation for each framework.

Repaintable in CSS

30 OKLCH tokens. Set one on :root and every component retunes at runtime. No rebuild, no Sass.

A spec, with code

v3 is the first implementation. React, Vue, and Base UI ports come later, all against the same spec.

Vanilla and small

No Bootstrap, no jQuery. BEM classes with Radix-aligned [data-state]. Around 28 KB gzipped for core.
