JavaScript Library & Framework
102,977 of the 1,000,000 top sites in our Tranco top-1M census run Swiper (10.3%). An open-source JavaScript library for building touch-friendly sliders and carousels. Detection is homepage-level HTML/header fingerprinting, so a site can run Swiper on other pages without it showing here.
