UPage is a visual web page builder powered by large language models (LLMs), designed to rapidly generate personalized, high-quality websites from natural language descriptions. It targets developers and creators seeking an efficient, intelligent workflow, offering a Lovable open-source alternative.

How It Works

The platform integrates with mainstream LLMs, translating user prompts into functional web pages via a WYSIWYG editor for real-time visual design. This approach combines AI-driven content generation with direct manipulation, enabling faster iteration and sophisticated design from simple text inputs.

Quick Start & Requirements

Deployment requires a Linux server with Docker. Installation uses a one-click script: bash docker run -d --name upage --restart unless-stopped -p 3000:3000 -e LLM_PROVIDER=OpenAI -e PROVIDER_BASE_URL=your-provider-base-url -e PROVIDER_API_KEY=your-openai-api-key -e LLM_DEFAULT_MODEL=your-default-model -e LLM_MINOR_MODEL=your-minor-model -v ./data:/app/data -v ./logs:/app/logs -v ./storage:/app/storage halohub/upage:latest Configure LLM access via environment variables. The UI is accessible at http://localhost:3000. An alternative installation is via the 1Panel app store. Detailed usage is in the UPage Online Documentation.
