I'm making a quick list to be sure to support projects that have a positive impact on my digital life, at the crossroads of selfhosting and privacy. Selfhosting is currently more of a hobby (fiddling, note-taking and media serving), and looking at my Portainer stack right now, I'm thinking of PiHole, Jellyfin, Homarr and Homepage. Some projects like FileBrowser, PiGallery2 and Audiobookshelf don't seem to have a way to contribute financially. Any well-know project that might be in near-critical condition/need of support? Which projects are you planning to donate to?

I have a few VPSes that can only be accessed via Wireguard (full-tunnel). A some hosted apps with external access are behind a Caddy authentication. None of this is possible with an cheap exotic VPS I got recently, because (1) it's KVM with Linux 4.19 kernel, implying no native Wireguard support, (2) I have access to only 10 ports, from 2101 to 2110, while Caddy needs access to ports 80 and 443, at least in my understanding. I've tried various tutos to compile and install Wireguard for old kernels, to no avail so far. I've also tried changing the port when installing Caddy, doesn't go through either. How would you people secure such a VPS like that? Nothing critical is hosted on it. Thanks in advance.
