Multi-Browser Viewer4 - Download

Multi-Browser Viewer is the first true cross-browser compatibility testing software package. Test any site by using real standalone browsers or using screenshot browser images (similar to Browsershots.org but higher reliability and quality).
Run IE6, IE7 and IE8 alongside each other and clearly see the different behaviors and functionality of a webpage. Test secure pages, JavaScript and general look and feel, without having to set up multiple virtual machines or using slow VNC connections.

Multi-Browser includes pre-packaged, virtualized standalone browsers, including IE6, IE7, IE8, and IE9 Safari, Chrome, Firefox and Opera. Each browser launches from a single executable that runs in its own virtualized sandbox, thereby maintaining its own default rendering engine and isolating the browser from the rest of your PC. All Standalone browsers come pre-installed with Adobe flash, to enable a user to test flash animations as well.

The Selenium RC integration enables users to Automate their cross and functional browser tests on a local, single machine seamlessly with no initial setup effort. Just Record, Copy and Paste the generated Selenium source code and then replay against any of the standalone browsers.

Aside from standalone browsers, Multi-Browser Viewer also has the ability to take screenshots in the widest selection of browsers across three operating systems (Mac, Windows and Linux). Loading a URL and taking a full-page screenshots. The screenshot images are then downloaded to your local machine for easy comparison. The most convenient way to do a quick, overview cross browser compatibility test of any website.
Multi-Browser Viewer also has a built-in HTML validation and auto correction feature, to help you identify any HTML errors that could be causing cross browser compatibility issues.
