¿Qué es?

OpenUI is a Generative UI framework for letting language models produce interface elements instead of plain text. Its core is OpenUI Lang, a compact streaming-first language. Developers define the components a model may use, the toolkit generates a system prompt from that library, and the streamed model output is parsed and rendered progressively as tokens arrive.

The framework-agnostic core is paired with runtimes for React, Vue, Svelte, and Angular. The React packages also include prebuilt chat layouts and two built-in component libraries covering charts, forms, tables, and layouts. Additional packages target LangChain and LangGraph agents, the A2UI protocol, email generation with React Email, and a browser bundle for CDN or iframe embeds.

The project reports that OpenUI Lang uses up to 67% fewer tokens than equivalent JSON, with a benchmark suite included in the repository. A CLI scaffolds a working chat app with a single command.

Funciones clave

  • 01Streaming renderer that displays model-generated UI progressively as tokens arrive.
  • 02Prompt generation directly from the component library you allow the model to use.
  • 03Runtimes for React, Vue, Svelte, and Angular on a framework-agnostic core.
  • 04Prebuilt React chat layouts and built-in charts, forms, tables, and layout components.
  • 05LangChain and LangGraph integration that streams OpenUI through AG-UI.
  • 06Zod-based typed component contracts for props and structure.

Casos de uso

  • Building an AI assistant or copilot that answers with interactive charts, forms, or tables.
  • Restricting model output to a vetted set of components in a production product.
  • Adding generated UI to a LangGraph agent backend with a React frontend.
  • Embedding generated interfaces in an iframe or static page via the browser bundle.
