Modify User Agents

Servers commonly use the User-Agent Request Header to identify their client's application type, operating system, software vendor, or software version. Based on the User-Agent string, the server selects suitable content to send in response. For instance, when a website opens on a mobile device, it usually looks quite compact and different from the way it opens on a desktop.

Now imagine if your browser allows you to override the User-Agent string, you could see any version of a website you like! All you need to do is to install Requestly extension in your browser and enjoy the fun. You can choose among popular devices like Android Phone, iPhone, tablets or web browsers like Internet Explorer, Safari, etc. Or you may also specify a Custom User-Agent string to experience a specific version of website.
