CSS & UI Framework
612 of the 1,000,000 top sites in our Tranco top-1M census run Chakra UI (0.1%). A React component library for building accessible, themeable user interfaces. Detection is homepage-level HTML/header fingerprinting, so a site can run Chakra UI on other pages without it showing here.
