localtunnel is a localtunnel client written in Golang.

localtunnel allows you to expose your localhost to the world for easy testing and sharing!

Download and put the binary somewhere in your path.

git clone http://github.com/jweslley/localtunnel
make build

Assuming your local server is running on port 8000, just use the lt command to start the tunnel.

lt -p 8000

Thats it! A tunnel will be created and the command output will be something like:

your url is: https://dlaaazhqwd.localtunnel.me

This URL can be used and shared to access your local service from anywhere in the world!

You can restart your local server all you want, lt is smart enough to detect this and reconnect once it is back.

You also can access your service with a custom subdomain. To this, you need the -s option:

lt -p 8000 -s ltdemo

Output:

your url is: https://ltdemo.localtunnel.me

To finish the tunnel just interrupt the program (Ctrl-C).

The localtunnel client is also usable through an API (for test integration, automation, etc).

import "github.com/jweslley/localtunnel"

...

var port := 8000
var tunnel := localtunnel.NewLocalTunnel(port)
var err := tunnel.Open()
if (err != nil) {
	fmt.Printf("your url is: %s\n", tunnel.URL())
}

...

tunnel.Close()

import "github.com/jweslley/localtunnel"

...

var port := 8000
var subdomain := "ltdemo"
var tunnel := localtunnel.NewLocalTunnel(port)
var err := tunnel.OpenAs(ltdemo)
if (err != nil) {
	fmt.Printf("your url is: %s\n", tunnel.URL())
}

...

tunnel.Close()
