Good to know before you install

It answers with the models in Ollama on this server, so install Ollama too and download a model from its Models tab. Its licence is source-available, not fully open source.

At a glance#

What it is: AI Chat AI

Updates: Automatic A backup is taken first, and it rolls back if the update fails
Backups: Included Part of the daily backup when that's switched on
Copies: One per server

There's no step-by-step guide for Open WebUI here yet. Everything below comes straight from the app catalogue, so it's what LibrePortal really does when you install it. For using Open WebUI itself, its own documentation is the place to go: github.com/open-webui/open-webui.

Addresses and ports#

Open WebUI has one port. LibrePortal picks a free port number for each when you install, so yours will differ from anyone else's. The Config tab's Network section shows them, and the app's Open button uses the right one. "Anyone" means it's reachable from wherever your server is reachable; you can make it private later.

What it is	Who can reach it	With a domain
Web Interface	Anyone	`chat.your-domain`

Settings#

In its config file#

Open WebUI's own settings aren't on the Config tab yet. They live in the app's config file, described here so you know they exist. How to change them.

Setting	What it does	Starts as
Name `CFG_OPENWEBUI_DISPLAY_NAME`	What this app is called on your dashboards. Leave empty to use its usual name	Empty
Show on the LibrePortal Dashboard `CFG_OPENWEBUI_SHOW_ON_DASHBOARD`	Whether this app gets a shortcut on the front page of the LibrePortal WebUI, separate from any Dashy dashboard Choices: true, false	`true`
Update Check `CFG_OPENWEBUI_UPDATE_CHECK`	Whether Open WebUI may ask GitHub if a newer version exists Choices: true, false	`false`
Community Sharing `CFG_OPENWEBUI_COMMUNITY_SHARING`	Whether Open WebUI offers sharing chats, prompts and models to openwebui.com Choices: true, false	`false`
Detailed logs `CFG_OPENWEBUI_VERBOSE_LOGS`	Whether Open WebUI writes its normal, chattier logs, including who connected, instead of only warnings and errors. Choices: true, false	`false`
Debug logging for 24 hours `CFG_OPENWEBUI_DEBUG_LOGS`	Turn on to see everything Open WebUI is doing while you look for a problem; it turns itself off after 24 hours. Choices: true, false	`false`

Works with#

These are the other apps Open WebUI knows how to work with. Once it's installed, its page shows the same list with whether each one is connected. How this works.

AI models: Chats with the models downloaded to Ollama. LibrePortal sets this up by itself when both are installed.
Ollama
Grafana: Shows dashboards for the apps that have one. works with every app
Prometheus: Collects metrics from the apps that can export them. works with every app
Uptime Kuma: Watches your apps and shows when one goes down. works with every app

Privacy and security#

All clear Open WebUI has analytics, its update check and community sharing switched off by LibrePortal, and may still download an embedding model from Hugging Face. Its licence is source-available, not a standard open-source one.

What leaves this server#

An embedding model is downloaded from Hugging Face the first time documents are used

What LibrePortal turns off#

Detailed logs and per-request access logging (switchable in Config)
Anonymous telemetry and Scarf analytics
Update check against GitHub (switchable in Config)
Sharing to openwebui.com (switchable in Config)

Licence: Open WebUI License (BSD-3-Clause plus branding-preservation clause) - source-available, not OSI open source. Audited: 21 October 2026. See the privacy of every app and the Promise.
