AB and Multivariate testing service/software. Suggestions?

So I'm trying to do some A/B and Multivariate testing with dynamic content (+site wide) and with Googles Experiments... I can't do multivariate at all and site-wide AB testing is more complicated than it should be. Now I'm looking for alternatives.

Currently I've seen:
convert.com - $140/m for 50k tested/m (Added bonus of GA integration)
optimizely.com - $359/m for 200k tested/m (multivariate starts at this pricing)
visualwebsiteoptimizer.com - $129/m for 30k
SiteSpect - Contact sales
WebTrends Optimize - Contact sales


Anyone know of an open source and/or free script to do this? Or atleast different companies that would preferably be cheaper? I need at the very least 30k/month.

Have you tried Google website optimizer? Its free and open for everyeone!


if not satisfied then you can have a look on performable or unbounce.


Do share your experience with us if you use any of them.


Best of luck

Google Website Optimizer was the one I had used and it's been disabled. Thus the search for a new platform.

Performable is $1000/month for multivariate. Definitely no.
Unbounce hosts the changed pages on their servers so I can't do dynamic changes. They don't support multivariate either ( http://support.unbounce.com/entries/307775-does-unbounce-support-multivariate-testing-mvt )
