Build generative UI with a single prompt — the open standard for AI-powered, streaming-first user interfaces

Overview

OpenUI is a full-stack Generative UI framework with a compact streaming-first language called OpenUI Lang, a React runtime with built-in component libraries (charts, forms, tables, layouts), and ready-to-use chat interfaces. It is up to 67% more token-efficient than JSON for structured UI generation. The framework lets you define components, generate prompt instructions from your component library, and render structured UI as the model streams its output. Key features include a streaming renderer that progressively updates the UI as tokens arrive, prompt generation directly from allowed components, built-in component libraries ready to use or extend, chat and app surfaces for assistants, copilots and interactive product flows, and a scaffolded quick-start app with npm create. OpenUI is MIT-licensed and actively developed by TheSysDev, with 7,900+ GitHub stars.
