Wappalyzer is a browser extension that uncovers the technologies used on websites. It detects content management systems, web shops, web servers, JavaScript frameworks, analytics tools and many more.

Adding a new application

• Edit share/apps.json
• Add a 16x16 PNG image to share/images/icons matching the application name.
• Provide the URL to the application's website when submitting a pull request.

Example:

"Application Name": { 
	cats:    [ "1" ], 
	headers: { "X-Powered-By": "Application Name" },
	url:     ".+\\.application-name\\.com",
	html:    "<link[^>]application-name\\.css", 
	meta:    { "generator": "Application Name" },
	script:  "application-name\\.js",
	env:     "ApplicationName",
	implies: [ "PHP" ]
	}

Wappalyzer is multi-platform. The main code lives in the share/ directory and platform specific code in drivers/. The sections below describe how to set up a development environment for the various existing drivers.

To keep files synchronised between drivers, run the links.sh script (UNIX-like systems only, Windows users can use links.cmd.)

Mozilla Firefox

• Place a file called [email protected] in the extensions directory in your profile folder (~/.mozilla/firefox/xxxxx.default/extensions/ on Linux) containing the full path to drivers/firefox.
• Restart Firefox
• Navigate to about:config and set extensions.wappalyzer.debug to true.
• Ctrl+Shift+J brings up a console for debugging.

Google Chrome

The Chrome version needs some love, if anyone wants to pick it up. It's currently not as feature-rich as the Firefox add-on (although partially due to API limitations.)

• Navigate to about:extensions
• Check "Developer mode"
• Click "Load unpacked extension..."
• Select drivers/chrome/

Bookmarklet

Beta version available for testing at wappalyzer.com/bookmarklet.

HTML

The HTML driver serves purely as an example. It's a good starting point if you want to port Wappalyzer to a new platform.

• Navigate to drivers/html/

PHP

The PHP driver requires the V8js class. Installing V8js using PECL on Debian Linux or Ubuntu should be very straight forward:

• # aptitude install php5-dev php-pear libv8-dev
• # pecl install channel://pecl.php.net/v8js-0.1.3
• # echo "extension=v8js.so" > /etc/php5/conf.d/v8js.ini

Runnning Wappalyzer from the command line:

$ php drivers/php/index.php wappalyzer.com

Running Wappalyzer inside a PHP script:

require('WappalyzerException.php');
require('Wappalyzer.php');

$wappalyzer = new Wappalyzer($url);

$detectedApps = $wappalyzer->analyze();

Mozilla Jetpack

Work in progress, experimental. See https://wiki.mozilla.org/Jetpack.
