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.
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.
