What is Wappalyzer?
Wappalyzer is a technology profiling tool that scans websites and reports the frameworks, CMSs, analytics tools, payment processors, and other software they run on, using a browser extension, a web-based lookup, and an API. Developers use it to research how a competitor's site is built, while sales and marketing teams use the same underlying data to build lead lists filtered by technology, geography, and traffic. The platform also offers CRM enrichment, email verification, and website alerts that notify a team when a prospect or competitor changes their tech stack. A free tier allows a limited number of lookups per month, with paid plans scaling lookup, list, and API credit volumes for larger teams.
