Switching User Agent in Browser

The User-Agent request header is most commonly used by servers to identify its client’s application type, operating system, software vendor or software version. Based on the User-Agent string, server selects suitable content to be sent in response. For instance, when a website is opened in a mobile device, it usually looks quite compact and different compared to the way it opens in 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.

Requestly has a simple rule builder where you specify the source request URL or domain and select type of User Agent. You may also choose whether to override User-Agent only for the website URL or for all HTTP requests originating from that page.

The best part of this extension is that you may run different rules for different websites simultaneously.

Requestly also has a great application in web-development where you usually want to test your website on different platforms.

The extension also allows to create rules to redirect requests, modify request/response headers and block requests for personal usage or web development. It also allows to host files to library and share rules with friends.
