We have added the ability to test any of your web designs or web apps, no matter where they are located. They can be on a development web server behind your firewall, they can be html files sitting on your desktop - if you have access to browse to these web pages, then you can test them with CrossBrowserTesting. You can now use the power of our hundred plus browsers installed across Windows, Mac, Ubuntu, and mobile configurations to test both public and private pages. These 'internal' pages can be tested with both the automated screenshot engine and the live, interactive testing.
