A/B testing plugin for grav?

Hi all

Is there a plug-in to support a/b testing of differences in users actions on two (or more) different versions of a site?

Or a tip to how I could do that easiest with grav?

Thanks in advance
Morten

PS: I've searched but my search terms not leading to anything.

There's no generic plugin, no. Depending on what you're trying to test, it's a trivial matter to write a plugin that flips a coin and alters the output accordingly. It's hard to be more specific about knowing what exactly you're a/b testing. There are a few different ways to approach the problem.
