Recently I spent an hour trying to get a bunch of "self hosted ngrok alternatives" to work and couldn't figure out any of them. Either I couldn't get them to compile or their documentation had me seriously fooled.

Then I found out how easy it was to set up ssh reverse tunneling. Sshd + systemd turned out to be all I needed for a pretty stable and persistent connection from anywhere. I was so satisfied to find that the most common tools out there could already handle this. Yay!
