I've been looking for a webproxy that would work with big websites like YouTube. So far I've found only very outdated and abandoned ones. Is there any up-to-date and actually functional webproxy I could host?

Edit: The reason I need this is that there are some locked up Windows computers I can't install any traditional VPNs on and that are used by non-tech-savvy people.

I can't pin the comment with the solution so here's the link
