I tried it, its great if you want to get started. or you want to run a vpn on a server that doesnt support wireguard. My main gripe with the client is that it can’t do high speeds, it’s just too cpu bound. Like going close to a gigabit transfer.
With wireguard I was able to get to 98% gigabit transfer. It was fine for a month I was using it, in the end I just setup a wireguard mesh with Netmaker.
There is headscale where you can run your own hosted central server, so you’re not using the tailscale one.
In the end netmaker did what I wanted, however they tend to introduce bit of changes in their releases, so if you’re not super technical it might pose a challenege with upgrading until they reach a super stable version. Like jump from 0.10.X to 0.20 had some big changes for the whole netmaker internals. Bit that does not impact wireguard connectivity.
