How do I check if a website is using Segment?

Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. The popup matches Segment'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 Segment version can Sourcemap Explorer detect?

Segment ships as a hosted customer data platform 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 Segment a SaaS or self-hosted?

Segment 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 Segment cost?

Segment's pricing model is documented as: mid, freemium, recurring. 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.
