Ever wanted to access a site that restricts access because of the browser you’re using or maybe view the mobile version of a site to save bandwidth? If so, a user-agent switcher is the way to go. A user-agent represents your browser when you visit a website, and a user-agent switcher changes your browser’s user-agent to that of another specified browser, tricking the site to allow you access.

A user-agent switcher can do so much as well. You can explore the mobile web freely, see what Google sees and Linux-users who are frequently blocked will especially like this app. Developers when checking their code in other browsers also love user-agent switchers.

Our guide will outline the 3 best user-agent switcher extensions for Chrome.
