I link to awesome-tunneling in my post :) I didn't know about that particular list until after I spent my night doing this.

I didn't know about headscale, that does seem pretty cool but I think MagicDNS also specifically would introduce a behavior that I didn't particularly want -- TLS certs being issued for my individual hosts, and thus showing up in cert transparency logs and getting scanned. Ultimately this is really only a problem in the first minutes or hours of setting up a cert, though.

Honestly I would probably recommend every other solution before I recommend my own. It was just fun to figure out and it works surprisingly well for what I wanted -- short lived development tunnels on my own infra with my own domain, without leaking the address of the tunnel automatically.
