OpenUI
Describe a UI in words, see it rendered live, and convert the HTML to React, Svelte or Web Components.
Self-hosted UI generator from Weights & Biases that works with OpenAI, Groq, Ollama and more.
OpenUI turns a text description into a live-rendered interface and lets you ask for changes. It suits front-end developers who want a v0-style component generator running on their own machine.
What it is
You describe a component, OpenUI renders it live, and you can request edits or convert the HTML into React, Svelte or Web Components. It connects to OpenAI, Groq, Gemini, Anthropic, Cohere, Mistral, any OpenAI-compatible endpoint, or local models through Ollama, with LiteLLM handling other providers.
Who it's for
It suits developers who want to prototype interface components and are comfortable running a Docker container or a Python backend. It does not suit anyone who needs a full app with a database, hosting and deployment, because the README covers components only.
Key features
Live rendered preview
Generated UI appears as you describe it, so you can ask for changes in follow-up prompts.
Framework conversion
Convert generated HTML to React, Svelte or Web Components.
Many model providers
Use OpenAI, Groq, Gemini, Anthropic, Cohere, Mistral or any OpenAI-compatible endpoint.
Local models via Ollama
Point it at an Ollama server to generate UI with models on your own hardware.
LiteLLM config support
Supply your own LiteLLM proxy config to reach other model services.

Our honest verdict
What's great
- It generates and previews UI in one window, so you see each change straight away.
- Converts output to React, Svelte or Web Components rather than locking you to one framework.
- Works with Ollama, so a local model can drive it without a cloud key.
- Apache-2.0 licensing means you can adapt it for your own team tools.
Where it falls short
- You need Docker, or Python with uv and git, and API keys for each cloud provider you want.
- Output quality depends on the model you connect; small local models give weaker UI.
- It generates components, not full-stack apps; there is no hosting or database layer in the README.
Pricing & license
OpenUI is free under Apache-2.0. The README links a live demo but shows no paid plan, so your only cost is running it and paying any model provider you connect.

FAQ
Can OpenUI use local models?
Yes. Install Ollama, pull a model such as Llava, and OpenUI lists it in the model selector.
Which frameworks can it output?
The README says it converts HTML to React, Svelte and Web Components.
Is there a hosted version?
The README links a live demo at openui.fly.dev; the supported way to use it fully is to run it yourself.
