Framote is new tool that helps you share “live” URLs that can be controlled remotely.
To get started, you can specify any website – say cnn.com – and Framote will create a unique URL for that site. You can share that URL with a group of people and everyone will see the same website on their screens. If you update the underlying website at your end, all the other screens are refreshed automatically.
The service is especially useful for testing responsive designs. You can have the main website on your desktop computer and load the corresponding Framote URLs on your tablets and mobile phones. If you open a different page on your desktop, the mobile screens are updated automatically.
Internally, Framote embeds the source website into an IFRAME and makes an AJAX request to check the actual URL every few seconds. If the source URL has been modified, the IFRAME’s source attribute on the client’s screen is updated almost instantly. The Framote dashboard will also show list of IP address and devices that are accessing your unique URL.
