Architected For Speed & Ownership
Built from first principles for developers who want complete control over their UI stack without the dependency bloat.
Components import ONLY React and a 7-line cn utility. No Radix, Lucide, or Framer Motion bloat slowing down your bundles.
Not a locked npm package where you wait for PR merges. Run the CLI or copy the raw .tsx files directly into your codebase.
Built on standard CSS variables with @theme inline. Seamless light and dark mode switching with tactile ink and warm paper tones.
WAI-ARIA roles, roving tabindex, focus rings, and motion-reduce fallbacks built directly into every interactive component.
