Monitoring & Error Tracking
5,421 of the 1,000,000 top sites in our Tranco top-1M census run Sentry (0.5%). An application-monitoring platform for tracking errors, exceptions, and performance issues in production. Detection is homepage-level HTML/header fingerprinting, so a site can run Sentry on other pages without it showing here.
