The current sea of web browsers is awash in promises, but what makes Firefox better then Internet Explorer? And is Google’s Chrome really any faster or better at rendering web pages then Safari? Neowin.net was looking to answer this very question when it authored an excellent roundup of browser rendering engines. The report helps to break down which browsers and applications make use of each of the four most prominent technologies: Trident (Microsoft), Gecko (Mozilla), Webkit (Apple/Google), and Presto(Opera). While both Trident and Presto are both closed source projects, Gecko and Webkit remain open source and are likely to be the basis of any future browsers entering the market. It is an excellent reference for users looking to switch browsers and is a reminder that we should pay attention more to the underlying engine being used then the name of the browser itself. Market share of the various engines is a very telling indicator of general compatibility on the web. It will also help you the next time a Mac head goes on rant over how much better Safari is than Chrome. You now have the tools you need to put him in his place.
