define test in app backend

[lury]

I'm trying to switch to ABBA from optimizely, cause i don't mind writing jquery test code on my own. Still, the main problem is that i'd like to define experiments on server side, not in js code snippet.

Current solution lacks flexibility, because i have to change the code, every time i want to change my test. It's an issue when you work with several clients, and don't controll website code.

I could manage this in Google Tag Manager, but A/B test scripts should load ASAP, and in GTM you cannot controll the order of firing scripts, and all A/B test vendors say, that GTM is not the right tool if you want to change page contents.

So the solution would be to add a parameter to javascript request, and concatenate test code, or request it from standard js.
You'd also have to add possibility to create experiments on the backend, but if now they're created on first request, it should be easy to simply make this request on the backend.

do you think it's possible?
