Framote is a tool to share multiple websites without the need for the user to reload or even touch a thing. Your Framote URL will have an initial embed website wich you’ll be able to change anytime at your Control URL. The devices which have the Framote URL opened will be updated almost instantly.
This tool is pretty simple, at least over the basics. It uses an iframe to load the embed website, and makes AJAX requests every 1.2 seconds to check the actual URL. If it has been modified, the script simply changes the src attribute. You can also take a look at Remote Preview.
