UI Libraries

Choose a component or icon library by visual language, use case, and provenance.

Proto UI is not one component library. It is a foundation for choosing the visual language that fits your product while keeping reusable interaction protocols underneath.

The entries below use each component library’s own prototypes. Lucide uses a neutral carrier for its icons. Credits distinguish the design references and icon sources from the Proto UI implementation.
