Web Framework
38,357 of the 1,000,000 top sites in our Tranco top-1M census run ASP.NET (3.8%). Microsoft's server-side web application framework for building sites and APIs on the .NET platform. Detection is homepage-level HTML/header fingerprinting, so a site can run ASP.NET on other pages without it showing here.
