Test responsive design

Test your responsive designs in several sizes simultaneously

This is a tool that allows you to test a website's responsive design. Unlike other similar tools, this one allows testing several sizes simultaneously, either most tipical sizes for mobile devices or a custom size manually set. You must take in consideration that the loading time is mulyiplied by the number of web devices shown. You can navigate each instance indepentently and a vertical scroll bar is shown. The horizontal scroll bar is shown when the responsive design fails.

Write the url of the website you would like to test in the url box. If you are testing a local website (you haven't uploaded it to an internet server yet) you should write the route to the file and the tool will automatically transform it into a valid local url.

Note: those webs that don't allow to be encapsulated (like google or yahoo) won't load.
