Monitoring & Error Tracking
1,753 of the 1,000,000 top sites in our Tranco top-1M census run Datadog (0.2%). A cloud monitoring and observability platform covering infrastructure metrics, application performance, and log management. Detection is homepage-level HTML/header fingerprinting, so a site can run Datadog on other pages without it showing here.
