Essential Firefox Plugin for Developers: Wappalyzer

Have you ever wondered what CMS a particular site was using? Or what stack a site was developed on?

Wappalyzer is a browser extension that shows you what software is used by a site.  The plugin is available for both Chrome and Firefox, and works as intended.

The website also shows you stats from the past 90 days of the most popular software used on the web.

Some interesting tidbits, WordPress accounts for 56% of CMS usage on the web, with Joomla next at 19% and Drupal at 9%.

Wappalyzer also has an interesting business model.  While they provide developers a very useful tool, they are also collecting the data and selling them as datasets.

All in all, I would highly recommend this browser extension be a part of any web users tools.
