Identify the software used on the websites you visit
In plain words
Wappalyzer is a tool that identifies the software and technologies used on websites. When users visit a site, Wappalyzer detects what frameworks, libraries, servers, analytics tools, and other software are powering it. The tool is designed for web developers, engineers, and anyone curious about a website's technical stack. It works as a browser extension or standalone application, making it useful for competitive analysis, security research, and technology research.
