Overview
Open WebUI is a self-hosted chat and RAG front end for Ollama, OpenAI-compatible or Anthropic-compatible backends. It suits marketers who want confidential client research and drafting to stay on their own machine. Its licence requires retaining Open WebUI branding for deployments of 50 users or more, so it is not OSI open source and white-labelling requires a paid arrangement.
Key Features
- ✓Self-hosted chat interface with built-in RAG over your documents
- ✓Full REST API with bearer-token or JWT auth
- ✓OpenAI- and Anthropic-compatible endpoints
- ✓Works with local Ollama models for zero per-token cost
- ✓Custom licence with a branding-retention clause (not OSI-approved)
