Full disclosure we are the developers of this app, but I’d like to let you know about Morpheusly, a new open-source app which allows you to access your computers from anywhere by creating Wireguard VPN tunnels.
Specifically to the question above, it tries to establish a peer-to-peer link and will thereby provide the lowest latency possible. It also avoids the use of SSH tunnelling which adds overhead.
To learn more, see our Morpheusly Beta Page and our Source code.
