Wappalyzer is a user-friendly Mozilla Firefox add-on that reveals the technologies behind any website. Once installed, it displays small icons in the lower right corner of your browser. Simply hover over these icons to discover if a site is using Google Analytics, jQuery, WordPress, Quantcast, and more. Ideal for programmers and website administrators, Wappalyzer helps you understand the tools and platforms powering each website. Enhance your web development and analysis skills with this straightforward and efficient tool.
Wappalyzer has some strengths, like ease of use, but there are a few features I found lacking. It provides good data, yet I wish it had more detailed explanations for technologies listed.
