Analytics & Tag Management
452 of the 1,000,000 top sites in our Tranco top-1M census run Heap (0%). A digital analytics platform that auto-captures user interactions for product and behavioral analysis. Detection is homepage-level HTML/header fingerprinting, so a site can run Heap on other pages without it showing here.
