My website has two designs and I not sure which one is better. I am thinking upload both of them.

Here is my question: Is drupal able to let 50% of the user see design A and the rest is able to view design B. After one month later, I am able to see a report which one is better.

ThemeKey allows you to define simple or sophisticated theme-switching rules which allow automatic selection of a theme depending on current path, taxonomy terms, language, node-type, and many, many other properties. It can also be easily extended to support additional properties exposed by other modules.


The closest thing I know is:


Adds a block to allow users to switch between enabled themes.

Themes can be given 'user friendly' names and access can be controlled by user role.

Switchtheme provides optional support for Browscap module to switch themes based on the browser of a visitor.

  • Didn't know about this one. Any criteria/suggestions about how to decide between this module and Themekey? Or should it post this as a new (official) question? Jun 10, 2016 at 5:06
  • @Pierre.Vriens idk the answer to that, so a new Q will be educational.
