Live interactive cross-browser webpage compatibility testing: Browserling
Browserling is a web app which not only allows to test compatibility on any web page with all of the different browsers and versions available out there, but it also allows you to actually interact with the page within your selected browser of choice.
In other words: you can see how any web page will look on any other device and you can also preview how any user will be able to interact with it.
browsers supported: Firefox, Chrome, Safari, Internet Explorer, Opera
OS supported: Windows, Mac OS, Linux
Free trial available (supports only Windows testing).
My comment: Excellent solution for web developers and webmasters to test the effective design compatibility of any web page across different browsers and operating systems. Recommended.
