OpenUI is an open-source, renderer-agnostic Generative UI framework built around OpenUI Lang, a compact streaming-first DSL that lets LLM agents compose interactive interfaces from your component library. It provides React SDKs, built-in component libraries, a streaming renderer, chat/agent interface surfaces, and developer tools, with integrations for LangChain, Vercel AI SDK, Mastra, and more.
Use cases
- build a chat app where the LLM renders interactive dashboards and forms
- let AI agents respond with UI components instead of plain text
- stream generative UI from an LLM into a React frontend
- create agent interfaces with artifacts like reports and slides
- reduce token usage for model-generated UI compared to JSON
- wrap my existing shadcn/ui or Material UI components for agent composition
- connect LangGraph or Vercel AI SDK agents to a generative UI frontend
When to choose
- you want LLM agents to render interactive, streaming UI in React
- you need token-efficient structured UI generation with built-in component libraries
- you want a production chat/agent interface with artifacts without building the shell yourself
- you use agent frameworks like LangChain, Mastra, or Vercel AI SDK and need a UI layer
When to avoid
- your app is not React-based (other framework support is community-maintained)
- you need a simple static frontend with no LLM involvement
- you want fully managed backend features without using OpenUI Cloud or self-hosting the backend layers
