About Wappalyzer

Wappalyzer helps sales and go-to-market teams understand what websites are built with. Founded by Elbert Alias in 2008, Wappalyzer turns public web signals into technographic data that teams use to find prospects, enrich records, and monitor market changes.

We track thousands of web technologies across millions of websites and combine that data with company and contact details. That helps teams identify accounts that match their ICP, research competitors, and act on changes faster.

Wappalyzer is available through our website, APIs, browser extension, and bulk data products. Whether you need a quick technology lookup, a list of companies using a specific tool, or ongoing monitoring, we make web technology data easier to access and use.
