CMS & Website Builders
607 of the 1,000,000 top sites in our Tranco top-1M census run Umbraco (0.1%). An open-source .NET content-management system used to build and edit websites. Detection is homepage-level HTML/header fingerprinting, so a site can run Umbraco on other pages without it showing here.
