HubSpot
HubSpot is a marketing and sales software that helps companies attract visitors, convert leads, and close customers.
What detecting HubSpot tells you about a site
HubSpot is a marketing, CRM and CMS suite, and its tracking and content layers are heavily instrumented, so detection is easy. The page typically loads the HubSpot tracking script from js.hs-scripts.com / js.hs-analytics.net, sets hubspotutk and __hs* cookies, and — if the pages themselves are HubSpot-hosted — serves assets from hs-sites.com and the hubspotusercontent CDN. Spotting it tells you a marketing or sales-driven organisation runs its funnel through HubSpot, with forms, lead scoring and email tightly coupled to the site.
The detail that matters for HubSpot
Separate two cases: HubSpot only as a tracking/forms script bolted onto a site built elsewhere, versus the whole site hosted on HubSpot's CMS (hs-sites.com asset hosts) — the latter means marketing owns the entire web property, not just analytics.
HubSpot in a real-world stack
When you find HubSpot, it rarely travels alone. Often alongside Google Analytics and a sales stack; when it is the CMS too, it replaces WordPress entirely.

Quick facts
How we detect HubSpot
Sourcemap Explorer carries 4 fingerprint signals for HubSpot, spread across 3 channels — javascript global, html source 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._hsq
window.hubspot
Substring or regex match against the page HTML — typically a unique class, comment marker, or asset path.
<!-- Start of Async HubSpot
Script URL pattern. Typically a CDN host or chunk path that ships with the technology.
\.hs-scripts\.com/
FAQ
How do I check if a website is using HubSpot?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. HubSpot's specific fingerprints here are javascript global, html source and script src url, and the popup flags HubSpot whenever any combination of them is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What HubSpot version can Sourcemap Explorer detect?
HubSpot ships as a hosted marketing automation 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 HubSpot a SaaS or self-hosted?
HubSpot 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 HubSpot cost?
HubSpot's pricing model is documented as: recurring, high. 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.
