Open WebUI (self-hosted, Docker) review: self-hosted ChatGPT-style app that cites your documents

Not sponsoredModels & AI Infrastructure

Tested on Linux · Freemium

Open WebUI is a self-hosted, ChatGPT-style app for Ollama or any OpenAI-compatible server, with document chat, web search and tools. It runs no chat models. We ran it in Docker on Linux, with a cloud model through our local Ollama.

The good

Document chat built in. Attach a PDF and it finds the passage itself, with a citation that opens the excerpt. All three answers were right, each in 3 to 9 seconds.
Ollama preset, any server. The model picker puts your Ollama models and any OpenAI-compatible server in one list. Missing models can be pulled from Ollama in the app.
No telemetry, one caveat. Telemetry is off and the only login is local. But the OpenAI connection is on by default and keeps calling api.openai.com. It checks GitHub for updates.

The not so good

Custom licence, not OSI. Since April 2025 the licence is custom, not OSI open source by its own docs. Above 50 users, changing the branding needs an enterprise licence. At home, nothing changes.
Heavy for one person. Heavy multi-user software for one person. Short questions become about 5,900 tokens. On cards under 24 GB like ours, Ollama’s 4,096 default cuts them quietly. Cloud models hide it.

Our verdict

Recommended

It found the passage itself, cited it and got all three answers right in seconds. But it calls OpenAI by default, is heavy for one person, and has a custom licence, not OSI open source.
