Wappalyzer uncovers the technologies used on websites

That silly counter at the bottom using a fixed formula to count up a random statistic for no reason:

http://wappalyzer.com/sites/default/themes/wappalyzer/js/cou...

Can anybody explain the point of that thing? I'm assuming they do not query sites one by one continuously either.

Online lookup tool which does not require Chrome or Firefox.

Some of the data here is a little suspect. Example "programming languages":

http://wappalyzer.com/categories/programming-languages

It says 90% of the web uses PHP, 8% Java and 2 % other.

More accurately: "Identify software used on a website which identifies itself openly somehow". iWeb isn't the most popular editor, but perhaps is the most popular to advertise itself in generated pages.

I'd love to see a search engine that crawls the source code of sites, so you could find great implementations of frameworks and plugins.

I prefer Chrome Sniffer.

I feel my browser is 'nude' without Wappalyzer. It does an excellent job of showing the icon for 'this is yet another Wordpress site', 'Drupal', '.net' and 'Magento' (amongst lots of others). This snippet of information is very useful to know if you are wondering 'how did they do that!' when you come across a very good site.

It is also useful for showing what javascript frameworks are in use (although this isn't as at a glance as the main CMS tool).

Beyond those two pieces of information I have no real need to use or fault Wappalyzer. It is simply brilliant.

Slightly off-topic, however, the favourite Chrome extension has to be Hover Zoom: http://hoverzoom.net/ - I find a computer/browser really lacking if it does not have that on it!
