Original GitHub issue: https://github.com/open-webui/open-webui/issues/5714

Bug Report

Installation Method

Docker

Environment

Latest Open-WebUI
Both Firefox and Chrome

Expected Behavior:

Visiting the API docs page would render the Swagger page.

Actual Behavior:

Swagger / API docs do not render.

Description

Bug Summary:
While Open-WebUI relies on FastAPI by default it requires internet to download the JS/CSS files for the Swagger docs.

This is heavily documented here: https://github.com/fastapi/fastapi/issues/608

And can be easily solved by using the fastapi offline package here: https://github.com/turettn/fastapi_offline

@tjbck There's a solution here that doesnt use a dependency:

https://github.com/fastapi/fastapi/discussions/8500#discussioncomment-5152408

The versions of the .js/.css files prob need to be updated since it was posted 2 years ago.

fastapi/fastapi#8500 (comment)

The versions of the .js/.css files prob need to be updated since it was posted 2 years ago.

Would suggest that tracking these updates is important, cybersecurity wise. The build process should probably pull the latest versions in automatically, subject to subsequent scans.

I tend to agree that using fastapi_offline here would mostly just introduce new supply chain security concerns, no guarantees of any improved maintenance, so that it's probably simpler to maintain this in-project for now.

Longer-term, the solution is probably to raise this issue with the fastapi team, and have them fix it there.

I has been brought up in the fastapi repo multiple times and there's still no built-in way of doing this.

Both Open-WebUI and Ollama use a ton of dependencie, I don't see anyone bringing up the "supply chain" concerns on those.

Whichever solution works, I just want to be able to use Open-WebUI offline as it's README says. That is currently not possible, a lot of features don't work at all.

I am also having trouble finding the API Docs in my locally hosted Open-WebUI instance.

http://localhost:3000/api/v1/docs returns

{"detail":"Not Found"}

Though the API is working. as described in the Link to the docs.

@semidark I was getting that error until I added an environment variable to docker run:

-e ENV=dev

Regardless, the swagger docs or any api docs do not load when self-hosted without internet access.
