PiVPN is great and was one of the first services I experimented with on my old Pi 3.

Now with wireguard existing I didn't feel the need for anything besides wg-quick or using wireguard directly. I didn't even know PiVPN got support for wireguard, but it's great that it got maintained for so many years.

PiVPN is a great project, sad to see it sunset but the reason to let it go makes sense.
