Donated once to this fantastic project. I have it running on a VPS+wireguard+firewall and all devices configured to use it even when I am out and about and using the mobile. It performs well enough that all of my family is on it now as well. It's chugging along fine on a 3$ a month VPS and accessible only when logged in via wireguard.

Wireguard is working so well, that I am now thinking of starting up additional services for the family to use. Voip/Filestore, pic library etc etc... all firewalled of course.
