JavaScript Library & Framework
718 of the 1,000,000 top sites in our Tranco top-1M census run Backbone.js (0.1%). An early, lightweight JavaScript framework providing models, views, and routing for building single-page applications. Detection is homepage-level HTML/header fingerprinting, so a site can run Backbone.js on other pages without it showing here.
