The Open Standard for Generative UI
About the project
OpenUI is an open standard and full-stack framework for generative UI: an LLM generates interfaces in the compact streaming OpenUI Lang, rendered in React, Vue, or Svelte. Aimed at developers of AI assistants and copilots who need controlled UI output from a model.
Useful for
- Scaffold a generative UI chat app via npx @openuidev/cli create
- Restrict model output to your component library and generate a system prompt
- Embed streaming OpenUI Lang rendering into an existing React chat

Growth looks organic: forks and discussion are in line with active projects, and stars arrive unevenly, the way people give them.
These are heuristics, not a verdict: we judge by the repository’s behavior, not by a list of stargazers.
