How to Test Website on Different Browser

Browser Shot

Browsershots makes screenshots of your web design in different browsers. It is a free open-source online service created by Johann C. Rocholl. When you submit your web address, it will be added to the job queue. A number of distributed computers will open your website in their browser.

First go to BrowserShots.org , you’ll see almost all of the available browsers are pre-selected. If you want to test all available operating systems and browser versions, simply enter your website URL into the open field and click “Submit.”
