A neat idea, but projecting all of these services onto localhost is a bit of a security nightmare. Have you considered looking at what something like Twingate does? Using the CGNAT IP space for the projection allows you to give every individual service its own IP address, which helps quite a bit in terms of allowing you to isolate the services from e.g. malicious web pages.
I'll take a look at what twingate does for sure, thanks for pointing that out.
A few things that worth mentioning for connet's current state - you can technically bind to any local IP, not just loopback (or listen to them all). You also have the option of directly running a TLS/HTTPS destination (for mutual TLS directly to the service) or source (e.g. for mutual authentication between your local listener and the outside world). Another option is to build your own client and define how you want to source traffic - maybe its part of your app and there are no sockets or anything - you just connect and start talking.
