Build Tools & Dev Infrastructure
13,096 of the 1,000,000 top sites in our Tranco top-1M census run Turbopack (1.3%). A Rust-based JavaScript bundler and build tool built by Vercel as a successor to Webpack, used in Next.js projects. Detection is homepage-level HTML/header fingerprinting, so a site can run Turbopack on other pages without it showing here.
