How do you determine what technology a website is built on? [closed]

Answer 1

Check out Chrome Sniffer, a great light-weight solution.

Answer 2

yes there are some telltale signs for common CMSs like Drupal, Joomla, Pligg, and RoR etc .. .. ASP.NET stuff is easy to spot too .. but as the framework becomes more obscure it gets harder to deduce ..

What I usually is compare the site i am snooping with another site that I know is built using a particular tech. That sometimes works ..

Answer 3

There is also W3Techs, which shows you much of that information.

Answer 4

Examining the cookies the site gives can reveal the underlying framework. CodeIgniter, for example defaults to a telltale ci_sessions cookie. Sites using PEAR Auth will do something similar.

Answer 5

I use WebParser (http://www.cybermake.com) that allows to determine the CMS used by a website. It allows to determine CMS for multiple websites as well as it can pull the list of websites from the search engines for a given list of keywords. Powerful tool.

Answer 6

I use 1 plug in for Firefox that gives me the IP and country for the hosting website and it's Web Server name called Domain Details, and for javascript framework I use WTFramework

I still need to wonder what script it was written on, but it is a start :)

Hope it helps.

P.S. the output will be something like this:
