I've contacted http://wappalyzer.com/
because their system does not detect WB.
So i've suggest to look for the word "WebsiteBaker" in domain.com/admin directly
But it does not work, as showed in the anwser i've got :
Wappalyzer doesn't make any page requests so it needs to be able to find some signature code by looking at any page, not just the admin section. A meta tag would help, or a specific class name etc. Do you know if this is present in WebsiteBaker?
I was about to answer that it's impossible because the templating system does not require any mark from the cms, and even with preinstalled template, there is no distinctive mark.
But before I anwser, I just want to know if I'm wrong in my anwser or maybe something you can think of ?
