🟦 ngrok

ngrok is a free service that allows exposing local ports to the Internet with little configuration. Not acceptable for production but great while developing prototypes.

# register/login at https://dashboard.ngrok.com/

# install ngrok
snap install ngrok

# authenticate your local installation to your account
# you get this from the ngrok dashboard
ngrok config add-authtoken <AUTH_TOKEN>

# forward local port 8080 to a publicly available address online
ngrok http 8080

# now you can access the local port from the reported address, something like:
https://<IDENTIFIER>.ngrok.io

You can list what is currently being forwarded through you account at:

• https://dashboard.ngrok.com/cloud-edge/endpoints

ngrok also has paid features, but I haven't used those.
