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.js
• 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/i },
	url:     /.+\.application-name\.com/,
	html:    /<link[^>]application-name\.css/, 
	meta:    { 'generator': /Application Name/i },
	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 system only, Windows user will have to manually copy the files across.)

Mozilla Firefox

• Place a file called wappalyzer@crunchlabz.com 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/

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/

Bookmarklet

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