WhichBrowser is a browser detection library for use on html5test.com. I wanted to add automatic collecting and reporting of test results, so you can compare the results of various browsers without actually having to test with each browser. For this to work we need to know to which browsers the recorded scores belong. Unfortunately there are quite a lot of pitfalls and if the recognition isn't performed properly the scores are attributed to the wrong browser making the whole thing completely unreliable.
So the first step is to create a "small" JavaScript library that parses the useragent string and reliably detect the proper browser, rendering engine and operating system. Additionally we need to detect the manufacturer and model for mobile devices and tablets because some manufacturers ship with modified rendering engines that support either less or more features.
This site it the result of that first step: it will tell you which browser you are using. The code will soon be available on Github.
