Compare Pages is a free Chrome add-on developed by LisL that allows users to view two web pages simultaneously on one tab. With the help of iframes, this application enables the display of two websites side by side, making it convenient for users to compare and contrast different pages.

One of the notable features of Compare Pages is its compatibility with sites that have the X-Frame-Options DENY option installed. This means that even if a website has restricted embedding, users can still view it using this add-on.

The application has undergone several updates to enhance its functionality. The recent updates include the ability to enter the URL of the page for comparison, the option to switch between panels with a button click, and the addition of a reference. Additionally, users can now view the page source code.

Compare Pages offers a simple and efficient way to compare web pages without the need to open multiple tabs. It is a useful tool for users who frequently need to analyze and compare different websites.
