Analytics & Tag Management
2,018 of the 1,000,000 top sites in our Tranco top-1M census run PostHog (0.2%). An open-source product-analytics platform combining event tracking, session replay, and feature flags. Detection is homepage-level HTML/header fingerprinting, so a site can run PostHog on other pages without it showing here.
