Open WebUI hosting in the EU

Open WebUI: A chat page like ChatGPT for the AI models you choose, with your chats kept on your own server. On blitz.cloud you install it from the App Store in one click. It gets its own address with HTTPS, 2 GB of storage, and it runs on servers in the EU. You can run it on the free plan, without a credit card.

A self-hosted alternative to ChatGPT, Claude, Gemini and LibreChat

Open WebUI does the job of ChatGPT, Claude, Gemini or LibreChat, but it is your own copy: your data sits in your app, not in somebody else's account, and nobody changes the price or the rules on you. Self-hosting usually means renting a server and keeping it patched. Here the App Store sets it up and keeps it running.

What it needs

Install it

1. Create a free account and open the App Store in the dashboard.
2. Search for Open WebUI, or for ChatGPT, and pick a name. It becomes the address, like open.yourname.blitz.cloud.
3. Click Put it online. The last step lists everything that gets created and how much of your plan it uses.
4. Open the app's address and create your account. The first account becomes the admin.
5. Under Admin Panel, Settings, Connections, add the API key of OpenAI or another compatible provider.

Good to know

It runs no AI model itself. You bring an API key from a provider, and searching your own documents needs an embedding key as well.

Questions

Can I host Open WebUI for free?

Yes. The free plan runs it without a card and without an end date. The app sleeps after 30 minutes without visitors, and the next visit wakes it.

Where is my Open WebUI data stored?

On blitz.cloud's servers in the EU, run by BlitzWorks, a company in Germany. Once signed in, you can download the data processing agreement as a PDF.

Can I use my own domain for Open WebUI?

Yes, on Pro, or on the free plan by making this one app a Pro app. HTTPS for the domain is set up for you.

Is Open WebUI backed up?

On Pro its files are copied every night and kept for 30 nights, and you can put them back from the app's page. On the free plan they are not copied, so keep an export of what matters.

How does Open WebUI get updates?

With automatic updates on, it gets new versions of its version line overnight. If a new version doesn't start, the one before it keeps running.
