HubSpot CMS Detector
Paste any URL and instantly see whether the site is built with HubSpot CMS — with the matched evidence.
We do not store the URL you audit. Want the full audit (performance / images / SEO / accessibility + real-browser speed test)? → run the full audit
Why check this
Confirm the platform first: CMS decides what can be changed and whether it is worth it.
What this is
HubSpot CMS keeps content, landing pages and marketing automation in one portal. B2B acquisition sites and resource hubs rely on it. Confirmation lets you separate hs-scripts, analytics and CTA modules from theme CSS and bill each line. Marketing owns publish cadence; engineering inherits every tracking script the portal injects.
How to tell from a public page
- [HubSpot CMS] Script hosts include `hs-scripts.com`.
- [HubSpot CMS] `hs-analytics.net` or feedback host `hs-feedback.com` appears.
- [HubSpot CMS] File paths include `hubspot.com/hs-fs`.
- [HubSpot CMS] Page modules carry HubSpot form or CTA embed markers.
How to read the result
Confirm when marketing script hosts reproduce; a footer that says powered-by without hs domains remains only suspected. Absence can mean a server-side container rewrote marketing script hosts. CRM case studies that mention the portal while the front end is custom mislead scanners. After a hit, audit consent ordering for chat and tracking.
What to do next
Trim tracking scripts, defer below-fold CTAs, and verify consent mode. Tagging often coexists with GTM — see Google Tag Manager detector. Full-site scoring is on run the full performance / images / SEO / accessibility audit on the home page. Hand HubSpot script-host evidence to marketing ops before deleting tags.

FAQ
How is HubSpot CMS detected?
From structural signatures in the public HTML and response headers (domains, paths, attributes, scripts). Every verdict lists how many times each pattern matched — nothing is guessed.
Can the result be wrong?
If only a bare brand keyword matches without structural evidence, we label it \u201clikely\u201d instead of \u201cconfirmed\u201d — we would rather under-report than cry wolf.
Do you save the URLs I check?
No. The audit runs inside the request and the URL you paste is not written to storage. There are no third-party tracking scripts on the page either, so no log of who checked what exists. Copy the result yourself if you want a record.
Can a website hide what it is built with?
Partly, but rarely completely. The HTML sent to your browser, the response headers, script paths and asset structure have to be exposed to work, so there is always something readable. Server-side code, build config and private APIs stay invisible. That is why this tool reports the evidence it found rather than claiming a full picture. No match does not mean the technology is absent.
