Datadog
Datadog is a SaaS-based monitoring and analytics platform for large-scale applications and infrastructure.
What detecting Datadog tells you about a site
Datadog's presence in the browser comes from its RUM and browser-logs SDKs — a script from a datadoghq / datad0g-style host and a global that batches performance, error and session data to Datadog's intake endpoint. Spotting it tells you observability is a first-class concern: Datadog is a premium, usage-priced platform, so a team running its browser SDK almost certainly also runs Datadog server-side for metrics, traces and logs. It points to an organisation with real ops maturity and budget, commonly mid-to-large SaaS and enterprise.
Datadog in a real-world stack
When you find Datadog, it rarely travels alone. The browser RUM is the visible tip of a full Datadog deployment — APM tracing, infrastructure metrics and log management on the backend.

Quick facts
Detection methodology for RUM
Analytics SDKs are usually loaded from a vendor-controlled CDN (`googletagmanager.com`, `google-analytics.com`, `cdn.segment.com`, `cdn.amplitude.com`, `eu.i.posthog.com`) and expose a global with a recognisable surface. We catch the script src URL plus the global plus — when a sourcemap is available — the exact `node_modules/<sdk>/package.json` version. Tracker isolation prevents these vendor libraries from polluting the surrounding stack readings.
How we detect Datadog
Sourcemap Explorer carries 3 fingerprint signals for Datadog, spread across 2 channels — javascript global and script src url. The exact patterns are listed below, and you can replay each one in Chrome DevTools to confirm a match by hand.
Each signal alone is rarely conclusive — Sourcemap Explorer cross-references all of them and weights by confidence. You can reproduce any of these checks yourself in Chrome DevTools.
Window-level global the technology installs on page. Reproducible by typing the path into the DevTools console.
window.DD_LOGS
window.DD_RUM
Script URL pattern. Typically a CDN host or chunk path that ships with the technology.

FAQ
How do I check if a website is using Datadog?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. Datadog's specific fingerprints here are javascript global and script src url, and the popup flags Datadog whenever any combination of them is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Datadog version can Sourcemap Explorer detect?
Datadog ships as a hosted rum rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
Is Datadog a SaaS or self-hosted?
Datadog is offered as a hosted SaaS product. Detection runs against the JavaScript SDK or asset-URL fingerprints the platform ships into pages.
How much does Datadog cost?
Datadog's pricing model is documented as: low, payg, recurring, freemium. Detection is independent of the pricing tier — Sourcemap Explorer flags the technology by its fingerprints, regardless of which paid plan a site is on. See the official site for the current pricing page.
