Lithos UI is a production-ready, Neo‑Brutalist React component library designed for high‑impact, high‑contrast layouts. It is built to prioritize architectural precision and developer velocity.
Zero‑Gap Architecture
We completely avoid the CSS gap property. Layouts are built using intentional, manual spacing logic for absolute structural integrity.
YIQ Contrast Engine
Accessibility is mathematically guaranteed. Our built‑in global engine automatically calculates whether text and borders should be black or white based on any background hex color you pass it.
Universal React Architecture
Framework‑agnostic and React Compiler ready. Whether you are building with Next.js, Remix, Vite, or Astro, our strictly separated context hooks guarantee flawless integration and perfect Hot Module Replacement.
