Wappalyzer
Wappalyzer turns public website signals into technographic data for prospecting, record enrichment and monitoring market changes. It identifies thousands of technologies across millions of websites using signals such as HTML, scripts, headers, cookies and other fingerprints. Users can upload CSV or TXT files with up to 100,000 URLs for bulk analysis. APIs cover technology lookup, lead lists, subdomain discovery and email verification. Live results count as five lookups each; cached results are verified within the last 30 days. The service offers browser extensions and integrations including Salesforce, HubSpot, Pipedrive, Gmail, Zapier, Make and an iPhone app. Basic extension detection runs locally, and sharing limited website-level data can be disabled in settings. The free plan includes 50 technology lookups and 50 email verifications per month, five website alerts and sample lead lists. Pro costs $250 a month for one user. Plan-included API credits expire after 60 days, while credits bought in bundles expire after 365 days. Wappalyzer is aimed at sales, marketing, operations, strategy, partnerships and security teams.
