Show HN: HTML5 API for multivariate testing

We created this project in response to seeing many clients making changes blindly based on gut feeling, and not being completely satisfied by the existing multivariate testing solutions. We wanted a simple way to write variants in HTML(or haml or jade).

For those of you unfamiliar with this design technique, new designs are tested on a statistically significant portion of your users to test for higher conversion rates.

It's also MIT licensed and works with google analytics: https://github.com/255BITS/xander

Thanks for any feedback you have!
