Open WebUI is an extensible, feature-rich, self-hosted AI platform that allows users to run and interact with large language models (LLMs) entirely offline or via APIs, prioritizing privacy and control.

---

🚀 Overview

Open WebUI provides a user-friendly web interface for self-hosted AI, enabling seamless integration with local runners like Ollama and cloud APIs like OpenAI, Anthropic, or any compatible service. It solves the problem of dependency on proprietary cloud AI services by offering full ownership, data privacy, and customization without compromises. Users can extend functionality with Python, leverage community-shared prompts, models, and tools, and scale from personal laptops to enterprise deployments.

It's built for developers, AI enthusiasts, and organizations—from startups to global enterprises—who want to run AI on their own infrastructure. The project empowers self-sufficiency in AI, supporting voice, vision, RAG, and more out of the box. Mission: "Open WebUI is being built so everyone can run AI for themselves. Not rent it. Not depend on it. Own it."

✨ Key Features

• Seamless integration with Ollama, OpenAI-compatible APIs (LM Studio, Groq, etc.), and bundled Ollama support for easy local setups.
• Advanced RAG with 9 vector databases (ChromaDB, PGVector, etc.), web search (15+ providers), and document loaders for knowledge retrieval.
• Multimodal capabilities: hands-free voice/video calls (Whisper, ElevenLabs, etc.), image generation/editing (DALL-E, ComfyUI, Stable Diffusion).
• Enterprise-ready: RBAC, SSO (OAuth, LDAP/AD, SCIM), audit logs, horizontal scalability with Redis/WebSockets.
• Extensibility: Python function calling, Pipelines plugin framework, model builder, PWA for mobile.
• Optional: Community marketplace for prompts/tools, multilingual support, OpenTelemetry observability.
