Open WebUI turns a model endpoint into a production-grade chat product. It’s the interface layer of choice for local-first teams.
Why it made the list
- Conversations, personas, multi-user workspaces, and permissions
- Built-in RAG with keyword + vector hybrid search
- Function/tool support (automatic tool calling on Ollama endpoints)
- Extensible via pipelines and UI forks
Best with
Ollama or any OpenAI-compatible backend — the pair is the (open) stack we recommend in Run Open-Source LLMs Locally.
