OpenUI is an open-source tool for rapidly generating and iterating on UI components using natural language descriptions. It targets developers and designers seeking to accelerate UI prototyping and development, offering a flexible way to translate imaginative ideas into functional code across various frameworks.

How It Works

OpenUI leverages large language models (LLMs) to interpret user prompts and generate UI code. It supports multiple LLM providers via LiteLLM, including OpenAI, Groq, Gemini, and Anthropic, and can also integrate with local models through Ollama. The system allows for iterative refinement of generated UIs by accepting further natural language commands and can convert existing HTML into different frontend frameworks like React, Svelte, and Web Components.

Quick Start & Requirements

• Docker: docker run --rm --name openui -p 7878:7878 -e OPENAI_API_KEY=xxx ghcr.io/wandb/openui
• From Source: Clone repo, cd openui/backend, uv sync --frozen --extra litellm, source .venv/bin/activate, set API keys, python -m openui.
• Prerequisites: API keys for desired LLMs (OpenAI, Groq, etc.), Ollama for local models.
• Resources: Docker image available. Development setup via Dev Container, Codespaces, or Gitpod is recommended.
• Docs: Frontend, Backend

Highlighted Details

Limitations & Caveats

The project is described as "not as polished" as commercial alternatives. Docker Compose setup may be slow, and GPU support for Ollama within Docker requires specific tag adjustments.
