Open WebUI
A self-hosted, feature-rich chat interface for local and remote models, the most common front door for a private assistant.
Open WebUI is a polished chat interface you run yourself. It speaks to Ollama and any OpenAI-compatible endpoint, so the same UI fronts a local model or a hosted one without changing anything users see.
It has grown well past a chat box: per-user accounts and roles, document upload with built-in retrieval, model switching, and a workspace for prompts and tools. For most teams it is the fastest way to put a controlled assistant in front of staff without writing a front-end.
Where it fits
The default choice when a team wants a private ChatGPT-style assistant inside its own perimeter, with accounts and document chat, and no front-end to build.
Where it does not fit
Not the right base when the assistant needs to be deeply embedded in your own product UI: at that point you want a component library, not a standalone app.

How it compares

We reach for LibreChat over Open WebUI when the client wants to own and shape the front-end code, not just configure a finished app.
