Browser Feature Support Tool

Want to know the percentage of your users that support modern browser features?

Well I do, so instead of looking at the metrics, compatibility tables and then going off to do some quick math I thought I would bite the bullet a built a tool that does just that.

Just show me the dam tool already! ok here: browser feature support tool.

Plug in your browser stats, select the features you want (for example CSS 3 declarations excluding implementations via IE filters), then hit go. If your using a decent browser your data will be stored and redisplayed to you the next time you visit.

At the moment the tool supports CSS2.1 selectors, CSS2.1 declarations, CSS3 selectors, CSS3 declarations, and you can display the results including or excluding IE filters and vendor specific properties.

Next stop is to add support for HTML5 and add IE9, FF4, Chrome 6 and Opera to the mix. I might add permalink support too as localStorage isn’t very portable.

Let me know what you think. And if you notice any buggyness please let me know too, it’s a V1 and hasn’t been tested much so far. Hope you find it useful however.
