CMS & Website Builders
340 of the 1,000,000 top sites in our Tranco top-1M census run Builder.io (0%). A headless visual page-building platform that plugs into existing frontend codebases. Detection is homepage-level HTML/header fingerprinting, so a site can run Builder.io on other pages without it showing here.
