# OpenUI

> OpenUI from Weights & Biases generates single UI screens from a text description and renders them live; you can ask for changes and convert the HTML to React, Svelte or Web Components. It runs locally in Docker or from Python source and works with OpenAI, Groq, Gemini, Anthropic and other LiteLLM providers, or Ollama. It does not build full apps: no backend, database or deployment. The README calls it "like v0 but open source and not as polished". The last feature work was in September 2025; 2026 commits are dependency pinning only. Apache-2.0.
