Open WebUI

What is Open WebUI?

Open WebUI is a self-hosted AI platform and chat interface for running local or cloud-based LLMs through a single web application. It supports Ollama, OpenAI-compatible providers, offline deployment, and multiple installation options including Docker, Python, Kubernetes, and a desktop application.

Key Capabilities

Multi-model chat: Users can chat with multiple model providers from one interface, compare responses, attach files, search the web, execute code, and use tool-enabled workflows inside the same conversation surface.
Knowledge and RAG: Open WebUI supports document upload, knowledge bases, hybrid search, multiple vector databases, and two retrieval modes: focused RAG retrieval and full-context document injection.
Agent and workflow support: The platform includes plugins, tool calling, automations, task management, agent connections, and extensibility for custom workflows.
Enterprise deployment: Open WebUI supports on-premise, private cloud, hybrid, and air-gapped deployments, along with identity integration, high-availability architecture options, and enterprise customization.

Audience & Use Cases

Audience: Developers, IT teams, platform teams, and organizations deploying internal AI systems with control over infrastructure and data.
Use Case: Open WebUI is used to provide internal AI chat, document question answering, model access, agent workflows, and self-hosted AI interfaces without requiring a separate frontend for each model or tool stack.

Currently, its available agents are Open WebUI's own cptr (Open WebUI Computer), OpenClaw, and Hermes Agent.
