About

OpenUI is a full-stack Generative UI framework designed as the open standard for model-generated user interfaces. It features a compact, streaming-first language (OpenUI Lang), a React runtime with built-in component libraries, and ready-to-use chat interfaces. It boasts up to 67% better token efficiency than JSON, enabling models to generate and progressively render structured UI from components. Key benefits include high efficiency, component-driven prompt generation, and controlled rendering.
