Kind of an odd question, and something I think is a long shot, but here goes.

I’ve long known and used GitHub pages for the odd static site, and generally like the service, Microsoft ownership aside, for the purpose of free hosting for temporary sites.

I was just trying to figure out how to host an instance of something for a popup event and wanted to be able to have a url that was mostly readable/recognizable. So my mind jumped to GitHub pages. I know it possible to connect GH pages to a custom domain, I used to host my personal website like this, but is the reverse possible? Can I expose my self hosted services on

user.github.io

in some way?
