Exposing local apps to the internet

This is probably the best and simplest way to expose a locally running app to the internet:

• nginx
• localtunnel
• cloudflare tunnels

And the app will be free, have SSL, no "warning page", and served via your custom domain.

DHH also quote-tweeted about this saying:

This is how we ran this year's Rails World campfire chat for a thousand attendees out of my closet in Copenhagen on a Beelink EQR5!

Crazy!

This is going to be very helpful for me in the coming days, as I am about to experiment with this a lot.
