Web Framework
1,370 of the 1,000,000 top sites in our Tranco top-1M census run Gatsby (0.1%). A React-based static site generator that pre-builds pages for fast-loading websites. Detection is homepage-level HTML/header fingerprinting, so a site can run Gatsby on other pages without it showing here.
