open-webui

Open WebUI is a self-hosted AI chat interface that connects to Ollama and OpenAI-compatible APIs. It delivers a ChatGPT-like conversational experience on your own server with complete data privacy.

• Multi-model support for switching between Ollama, OpenAI, Anthropic, and other LLMs
• RAG integration with document upload for AI-powered knowledge base queries
• User management with multi-user accounts, role settings, and shared chats
• Plugin system with tools, functions, and pipelines for extensibility
• Model management for downloading, updating, and removing Ollama models via UI
• Markdown and code support with syntax highlighting and LaTeX math rendering
• Voice input/output with speech recognition and text-to-speech conversation

Built with Python and SvelteKit, Open WebUI launches with a single Docker command. Combined with Ollama for local LLMs, it creates a fully private AI environment where no data leaves your infrastructure.
