Platform Overviews
HubSpot CMS
HubSpot CMS Hub is a content management system built natively into HubSpot's marketing platform — enabling marketing teams to build, manage, and personalize website content alongside their CRM, email, and analytics in a single platform. It's used by B2B companies that want tight integration between their website content and their sales pipeline — showing different content to known contacts versus anonymous visitors. HubSpot CMS pages load scripts from hs-scripts.com (HubSpot's tracking script CDN) and cdn2.hubspot.net for module assets. The markup includes hs-cta- prefixed class names for HubSpot's call-to-action widgets, hs-sites-specific data attributes, and the HubSpot tracking cookie infrastructure. The _hsp and _hsq JavaScript objects appear on all HubSpot-tracked pages. HubSpot CMS pricing starts at $25/month with the Starter tier.
