One of my best finds of the 2014 was Ngrok, service providing secure tunneling from your local machine to the web. It allows you to expose your locally running server to on-line in just a seconds, moreover you are able to access it on http and https. Each developer can find multiple use-cases for this kind of service.
It's multi-platform, stable, simple to use and free of charge service. Of course if you need, you can buy a license but you don't need to.
