Ask HN: What a/b testing framework do you use? 9 years ago
Hey dpix, so full disclosure I work there but we (Kameleoon) tick your boxes too ;)
And we do have an awesome customer success team that can do either classic support or handle your testing for you.
But I'm obviously biaised so you'll have to check it out yourself :)
Usual suspects are: VWO, Optimizely, Adobe target, Oracle Maxymiser.
