I am looking for some recomandations to add more wireguard servers. Right now I only have a few protonvpn free servers.
If you don’t mind paying for the service, there’s Mullvad.
If you don’t need port fowarding for torrents, I recommend Mullvad.
I swapped to AirVPN after Mullvad dropped port forwarding. AirVPN app on Android & Linux kinda sucks. Linux one is usable at least. The Android one is just bad, but I just use the Wireguard app instead of the AirVPN app.
