uikit

uikit is an open-source library that provides a collection of pre-built, customizable UI components designed specifically for use with react-three-fiber, enabling developers to create interactive 2D user interfaces within 3D scenes. It is built for React developers and 3D artists who want to add functional, stylable menus, buttons, and text overlays directly in WebGL without leaving the React ecosystem. Its interesting because it bridges the gap between traditional web UI and immersive 3D environments, making complex spatial interfaces as easy to build as standard React apps.
