What detecting Zendesk tells you about a site
Zendesk is a customer-support suite, and on a marketing or product site you almost always detect its widget rather than a whole Zendesk-hosted site. The tells are the Web Widget script from static.zdassets.com (ekr/snippet.js), a window.zE / zEmbed global, and embedded help-centre content from a *.zendesk.com subdomain. Spotting it tells you the company runs its support, ticketing and help centre through Zendesk — a signal of an established business with a real support operation rather than an email-only contact form.
Zendesk in a real-world stack
When you find Zendesk, it rarely travels alone. Frequently alongside a separate analytics/CDP stack and a marketing CMS, with the help centre (Guide) hosted on a Zendesk subdomain.

Quick facts
Detection methodology for Documentation
Live chat widgets are usually loaded asynchronously via a small bootstrap script and identify themselves through a vendor-specific runtime global. Intercom's `Intercom` global plus `widget.intercom.io`; Drift's `drift.load` plus `js.driftt.com`; Crisp's `$crisp` plus `client.crisp.chat`. We pick up the vendor and — when sourcemaps are available — the SDK version, which is meaningful when chat features change between major releases.
How we detect Zendesk
Sourcemap Explorer carries 6 fingerprint signals for Zendesk, spread across 4 channels — response header, cookie, 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.
Server-side fingerprint: the response header reveals the technology behind the page. Visible in DevTools → Network → response headers.
x-zendesk-user-id:
Cookies set by the platform. Visible in DevTools → Application → Cookies.
_help_center_session
_zendesk_cookie
_zendesk_shared_session
Window-level global the technology installs on page. Reproducible by typing the path into the DevTools console.
window.Zendesk
Script URL pattern. Typically a CDN host or chunk path that ships with the technology.
static\.zdassets\.com
FAQ
How do I check if a website is using Zendesk?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. Zendesk's specific fingerprints here are response header, cookie, javascript global and script src url, and the popup flags Zendesk whenever any combination of them is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Zendesk version can Sourcemap Explorer detect?
Zendesk ships as a hosted documentation 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 Zendesk a SaaS or self-hosted?
Zendesk 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 Zendesk cost?
Zendesk's pricing model is documented as: low. 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.
