HubSpot is a marketing with an AI Score of 10/100 (Unknown). Our detection engine uses 4 signal patterns to identify HubSpot-built sites.
Bolt is an AI-powered website and application builder developed by StackBlitz, primarily used by developers and technical users who want to rapidly prototype and deploy full-stack web applications directly from natural language prompts. The platform generates production-ready code in the browser, making it a distinctive target for detection due to its tight integration with StackBlitz's runtime infrastructure. AIWebsiteDetector's detection engine identifies Bolt-built sites through a combination of 3 script patterns, 3 HTML patterns, and 2 meta tag patterns embedded in the page markup, alongside 2 CDN domains that consistently appear in asset delivery and 2 HTTP response headers that expose the underlying platform. These signals work in combination to produce reliable detections across a range of project types, from single-page applications to more complex full-stack deployments. Bolt sites are characteristically hosted within the bolt.new ecosystem or exported to connected deployment targets, and the platform's deep reliance on WebContainer technology leaves consistent, identifiable fingerprints across both the DOM structure and network layer that distinguish it cleanly from other AI website builders.
HubSpot is an all-in-one inbound marketing, sales, and CRM platform widely adopted by small-to-midsize businesses and enterprise marketing teams for managing campaigns, landing pages, email automation, and customer pipelines. AIWebsiteDetector.com identifies HubSpot-powered sites through a combination of 3 distinct script patterns and 1 HTML pattern embedded within page source code, typically including references to HubSpot's proprietary JavaScript tracking library loaded from their CDN infrastructure, along with characteristic markup attributes injected into the DOM by the platform. These signals are highly reliable indicators because HubSpot consistently injects its analytics and forms SDK — most notably the `hs-scripts.com` CDN domain and the `hubspot-messages-iframe-container` HTML element — across virtually all sites built or tracked on the platform. The detection engine cross-references these patterns to establish confident identification, making HubSpot one of the more straightforward platforms to fingerprint due to its consistent and opinionated approach to front-end asset delivery. HubSpot operates as a hosted SaaS platform with tiered pricing ranging from a free CRM tier to premium Marketing Hub plans, meaning detected sites are always cloud-hosted under HubSpot's infrastructure rather than self-hosted, which further reinforces the reliability of its signature technical footprint.
