Web Framework
13,475 of the 1,000,000 top sites in our Tranco top-1M census run Ruby on Rails (1.3%). A server-side web application framework written in Ruby, following a convention-over-configuration philosophy. Detection is homepage-level HTML/header fingerprinting, so a site can run Ruby on Rails on other pages without it showing here.
