I built this to try to get most of the advantages of both ngrok and ssh -R at the same time. Like ngrok, you get an https subdomain that anybody can hit, but there's nothing to install—you use your SSH client to connect.

Next I'm working on an SSH-delivered terminal GUI for inspecting and replaying HTTP requests to match more of what ngrok does.

Great stuff, I was trying to find something like this for days. Is there any other website, where I could keep track of new features?

This is all at the moment! I'll add a changelog to that page.
