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