Hopefully I'll make it on the hall of fame [1] :)
may I ask why?
I do think it missing the point a tiny bit though. For me the primary use of Ngrok is to automatically get sub a domain with TLS and this seems to be outsourcing that to Caddy. And also I need to run a server. If I was going to run a server and run caddy I'd probably just use SSH -L directly.
Also SSH -L is a TCP/IP level tunnel so I'm missing something regarding why the HTTP/2 multiplexing is necessary vs just using the tunnel as is.
