Use Cases & Benefits
- Provides a full-stack generative UI framework with a streaming-first language, React runtime, and built-in component libraries for efficient model-generated interfaces.
- Delivers up to 67% token efficiency over JSON by streaming structured UI output incrementally and controlling rendering with typed component contracts.
- Use for building interactive chat and assistant interfaces that progressively render AI-generated UI components in React.
- Use for creating token-efficient dashboards and data visualizations with streaming charts, tables, and forms generated by large language models.
- Use for scaffolding end-to-end generative UI apps with CLI tools and ready-to-use component libraries across React, Vue, and Svelte frameworks.

General guidance from repository metadata, not legal advice. How we score
From the README
OpenUI is a full-stack Generative UI framework — a compact streaming-first language, a React runtime with built-in component libraries, and ready-to-use chat interfaces — that is up to 67% more token-efficient than JSON.
At the center of OpenUI is OpenUI Lang: a compact, streaming-first language for model-generated UI. Instead of treating model output as only text, OpenUI lets you define components, generate prompt instructions from that component library, and render structured UI as the model streams.
This is the fastest way to start with OpenUI. The scaffolded app gives you an end-to-end starting point with streaming, built-in UI, and OpenUI Lang support.
