It's amazing

Best extension to detect technologies but it's quite heavy in performance and sometimes a bit buggy.

It does not work most of the time. Use BuiltWith instead.

Very handful, but requires suspiciously many permissions.

Wappalyzer has always been one of my 'must-have' add-ons, but recently it became too heavy on resources!
I find my laptop fan spinning too much while doing nothing, and after I opened Firefox' `about:config` I found this addon uses a most of resources.

I use it, Very helpful and easy to use.
