Localtunnel is Ruby Gem, in fact, a real gem that allows you to make your localhost web applications live in a matter of seconds. It, actually, provides you a public tunnel for your local web server so you can provide the actual production environment to your web application right on your personal computer.
Localtunnel gives you a smart URL that is accessible over the Internet. Thus, you can see how your web application would actually behave when hosted publicly. With this smart feat, you can test and debug various scenarios that you have not encountered in your local environment. Making your local web server public also allows you to use your personal computer for conducting demos of your web application running in the real-world environment.
Implementing local tunnel is as quick and easy as pie
