BuiltWith

What it is.

BuiltWith profiles the technology running on any website. Its plans page says individual site lookups are free to use forever. Paid plans start at $295 a month and can be canceled at any time.

Enter a domain and you get its detected stack grouped by category, spanning analytics, advertising, hosting and CMS. The index tracks 124,000+ web technologies across data from 491.9 million domains. The underlying webpages refresh weekly.

Paid plans add lead lists and CRM syncing, plus trend history going back 18+ years. Exports go out as Excel or CSV, and report downloads are unlimited.

What you get.

  • A free technology profile for any single domain you look up
  • Detections grouped by category: analytics, advertising, hosting, CMS and more
  • Live website counts per technology, so you can size a stack's install base
  • On paid plans, lead lists keyed to technologies and keywords
  • Excel and CSV export with unlimited report downloads on paid plans
  • CRM integrations for Salesforce, HubSpot, Zoho, Dynamics 365, Pardot and Close.io
