I tried installing openwebui once. I gave up after the first 12 gigabytes of pip packages. Made my own LLM chat UI in 500 lines of HTML/JS. That's really all I needed.

This project does look fun though.

Open webui isn't fully open source, because it doesn't allow you to change or remove Open Webui branding.

I don't know if that was a motivation for creating this, but it is a reason some people might choose not to use it.
