Inspired by
https://medium.com/@shazow/ssh-how-does-it-even-9e43586e4ffc and ngrok, I made this SSH server that assigns a public url for each remote port forwarding request you make. Start a web server on 8080, then try this:
ssh -R 80:localhost:8080 serveo.net
It's an attempt to make port forwarding as easy as ngrok or localtunnel, but using the SSH client you already have.
Also includes HTTP inspection and replay like ngrok.
