A/B Testing & Personalization
790 of the 1,000,000 top sites in our Tranco top-1M census run AB Tasty (0.1%). An A/B testing and website personalization platform for running experiments and tailoring content to visitors. Detection is homepage-level HTML/header fingerprinting, so a site can run AB Tasty on other pages without it showing here.
