Web Server
325 of the 1,000,000 top sites in our Tranco top-1M census run Gunicorn (0%). A Python WSGI HTTP server commonly used to run Django and Flask applications in production. Detection is homepage-level HTML/header fingerprinting, so a site can run Gunicorn on other pages without it showing here.
