Passageway -- instant public tunnel to your local web server


Now you can install Passageway with RubyGems:

% gem install passageway

or to get the source:

git clone


passageway [options] <localport>
  -k, --key FILE    upload a public key for authentication

Passageway is a client to a free and open source reverse tunneling service made specifically for web traffic. It's intended to be used to temporarily expose local web servers to the greater Internet for debugging, unit tests, demos, etc.

This is how you make your local port 8080 public:

$ passageway 8080
Port 8080 is now publicly accessible from ...

$ passageway 8080
Port 8080 is now publicly accessible from ...

Using Passageway is comparable to using SSH reverse/remote port forwarding on a remote host that has GatewayPorts enabled, but without all the configuration or the need of a host. The localtunnel command works with a server component that is running on, which is provided as a free service.

If you have never run localtunnel before, you'll need to upload a public key to authenticate. You do this once:

$ passageway  -k ~/.ssh/ 8080

After that, you shouldn't have to use -k again.

Passageway can be started before or after the local web server. It tunnels through to the url given in that status message "publicly accessible from..." for as long as the command is running. The tunnel is closed if the command exits.

Passageway will search for the file .localtunnel_callback in the current working directory. If it exists, it will execute the file with one argument, the public endpoint, when the tunnel is opened. This is useful for starting other tools or processes that need the name of the endpoint.
