Web Server
2,711 of the 1,000,000 top sites in our Tranco top-1M census run Envoy (0.3%). An open-source edge and service proxy originally built at Lyft, often used as an API gateway or load balancer. Detection is homepage-level HTML/header fingerprinting, so a site can run Envoy on other pages without it showing here.
