Testing and developing a web service. Run the service on your localhost, like straight from your IDE with a debugger attached, and get a public internet facing bore.pub address for it. You can then point anything at it--your staging/integration or even production service, or maybe just a friend or coworker who wants to see in development work.

Yep, those are all good use cases where TCP tunneling comes in handy — basically, how can I get someone to connect to me?

For me to use it it would need to support https and 443 on bore.pub

Unfortunately this is explicitly out of scope for the implementation, but feel free to check out many of the more complex or commercial alternatives

I really like to test postback integrations with services like that
