JavaScript Library & Framework
412 of the 1,000,000 top sites in our Tranco top-1M census run Instant.page (0%). A script that preloads pages on link hover to make navigation feel instant. Detection is homepage-level HTML/header fingerprinting, so a site can run Instant.page on other pages without it showing here.
