Current prerelease is 1.2.5
1.2.4 is the first to introduce experimental Wayland support. Especially on KDE Plasma there are supposed to be some issues.
Lets test!
Why?
Regular RDP/VNC programs are hard to use in real scenarios, as they rely on IP addresses. RustDesk is easier as it uses a Rendezvouz server that can also be selfhostet or reimplemented.
The one big thing they do hide behind Pro though, is authentication for the server side. With the free version, if your server is open to the internet, then anyone who knows the IP can use it to relay their clients as well.
They still need to know the key. If you publicly distribute your config, that’s a problem. But IMO one even the pro version couldn’t solve.
