How wappalyzer(Mozila addon),GTmetrix finds the cms platform

Question

I am currently developing a site which is not supposed to expose its developer magento platform(Sorry about that ).

I thought the wappalyzer(Mozila addon),GTmetrix site is finding the cms names by its html format but when i saw a empty white page with that tools it still shows me like am using Magento(there is nothing in the source view - its white page), so now how they are finding that am using magento. Any idea about hw they are working? I checked headers but there nothing specially mentioned as magento. Same goes with wordpress/joomla - simply wappalyzer(Mozila addon),GTmetrix finds the site platform even there is no html source.

So I guess something with in header(i might missing something) or what it can be? please advice. Attached screenshot of it.

Thanks in advance

Answer 1

You can view Wappalyzer's source code: (Ctrl+F Magento):

https://github.com/ElbertF/Wappalyzer/blob/master/share/js/apps.js

Most likely Wappalyzer picked up on the "Mage" JavaScript variable. You can see this by clicking the DOM tab in Firebug.

Answer 2

They are finding it using the words like mage,varien,magento. If it finds any of these words inside css/js file class,#id,inside comment then it found it as magento.

Also gtmetrix does one more step , like it is checking the css/js url path - if it fins the url like skin/frontend then it says it as magento.
