I use it for a simple use case of connecting to my home assistant server from outside my network without having to open ports.

I just installed the tailscale app on my home assistant server (ubuntu) and then installed it on my iPhone. Then once they're both logged in I can use the IP address in the tailscale app to connect to the server from anywhere.

Like mentioned in the article it just works and is perfect just the way it is, for free. I don't need any extra features or improvements.
