Headless UI kitv0.1
The quiet power behind serious product UI.
Hyunsui keeps interactivity decoupled from style. Compose state machines, orchestrate focus rings, and keep your brand untouched across projects.
State preview
Composable primitives
Ship UI logic without dictating markup. Build anything from switchers to multi-step flows.
Headless by design
Render functions only return state. Styling stays under your full control, even per breakpoint.
Useful defaults
Focus on interaction. Keyboard focus, a11y attributes, and async orchestration are wired in.
Launch-ready
Bring Hyunsui into your next Next.js build.
Start with composable primitives, then extend with your design system.
