About Wappalyzer

Wappalyzer provides technology lookup and technographic data on websites, identifying the tools, platforms, and services a given site is built with. It offers lead list building, letting sales and go-to-market teams filter and export prospect lists by technology, keyword, market, traffic level, geography, and company data such as size, industry, and location, along with associated contact details including email and phone numbers.

The product also includes website alerts that monitor tracked domains for technology changes, such as migrations or newly added tools, and an email verification feature aimed at reducing bounce rates. Data can be accessed through bulk domain list analysis or an API for integration into CRM and outbound workflows.
