Monitoring & Error Tracking
1,102 of the 1,000,000 top sites in our Tranco top-1M census run Bugsnag (0.1%). An application error and crash monitoring service that reports and diagnoses issues in web and mobile apps. Detection is homepage-level HTML/header fingerprinting, so a site can run Bugsnag on other pages without it showing here.
