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
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. The popup matches Datadog's fingerprint signals (response headers, asset URL prefixes, runtime globals, sourcemap paths) and flags it whenever any combination 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.
