Serveo

Use it like `ssh -R 80:localhost:8888 serveo.net`. When you establish an SSH connection to serveo.net, a subdomain is assigned to forward HTTP (and HTTPS) traffic to your local server. Basic usage is as follows: `ssh -R 80:localhost:8888 serveo.net` The `-R` option instructs the SSH client to request port forwarding from the server and proxy requests to the specified host and port (typically localhost). A subdomain of serveo.net will be assigned to forward HTTP traffic. Multiple port forwards can be requested at once: `ssh -R 80:localhost:8888 -R 80:localhost:9999 serveo.net` The target server does not have to be on localhost: `ssh -R 80:example.com:80 serveo.net` Subdomains are deterministically selected based on your IP address, the provided SSH username, and subdomain availability, so you will usually get the same subdomain between restarts. You can also request a specific subdomain (from a predefined list): `ssh -R incubo:80:localhost:8888 serveo.net` `ssh -R incubo.serveo.net:80:localhost:8888 serveo.net` Change the SSH username to assign a different subdomain: `ssh -R 80:localhost:8888 [email protected]` Ports other than 80 may be requested, and raw TCP traffic will be forwarded. (In this case, connections cannot be routed by hostname, and the host—if specified—will be ignored.) `ssh -R 1492:localhost:1492 serveo.net` If port 0 is requested, a random TCP port will be forwarded: `ssh -R 0:localhost:1492 serveo.net`

Serveo is an SSH server for exposing local servers to the internet, forwarding HTTP/HTTPS/TCP traffic with public URLs—no installation or registration needed.
