Open WebUI started as Ollama’s web frontend and grew into a full LLM client: multi-user accounts, RAG knowledge bases, tool calls and Python “Pipelines” middleware. For air-gapped or fully on-prem customer scenarios, it is the de-facto choice alongside local LLMs.
Watch the branding terms#
Starting v0.4.0 the license added branding requirements:
- Deployments serving 50+ users must retain Open WebUI branding
- Commercial deployments need a separate license
