In cross-browser compatibility testing, it is necessary to have several environments set. Although having virtual machines is a good choice, it often becomes a hassle to switch between environments. There are some helpful tools that can reduce all this configuration work.

Netrenderer is a tool that allows you to check how a site is rendered in different versions of Internet Explorer. You don’t need to have an account or download a program. Just type in the URL to be tested, select the Internet Explorer version and the page will be rendered. This tool is recommended for testing specific sections of a page.
It avoids the necessity of having a virtual machine to install the desired browser version
Rendering takes seconds to be executed
It lets you compare between browser versions (IE6 – IE7)
Renders only one page at a time
It doesn’t show the complete page, making it necessary to add a vertical offset value to see the content
Incompatible with internal network sites
2. Browser shots

To use, just insert the URL, choose the browsers, and set the options mentioned before. When the screenshots are done loading, it shows a report of uploaded, available and expired browsers. You can  download them all in a zip file if needed.
