Tracking Company Finder

About

Tracking Company Finder is a simple JavaScript bookmarklet that displays an alert of all companies with tracking scripts found on your current page. It works by searching through all of the script and image tags on a website and checking if the source matches any known tracking domains.

The bookmarklet is still in development, since tracking urls and companies are still being added to the list. Feel free to edit the source code to add any scripts or companies you would like to include in the alert.

To use the bookmarklet, simply drag and drop this link into your bookmarks bar. Tracking Script Finder
