Platform Overviews
Base44 AI
Base44 AI is an AI-powered website builder designed for developers and non-technical users who want to rapidly generate and deploy functional web applications from natural language prompts. The platform produces identifiable front-end output that AIWebsiteDetector.com's engine reliably fingerprints through a combination of 2 distinct script patterns embedded in page source, 2 CDN domains used to serve Base44 assets, 2 characteristic HTML patterns in the document structure, and 1 meta tag pattern injected into generated pages. These signals appear consistently across Base44-built sites, allowing the detection engine to cross-reference multiple indicators simultaneously for high-confidence identification rather than relying on any single marker. The CDN domains in particular serve as strong anchors, since Base44 routes static assets and runtime dependencies through infrastructure that is distinctive to the platform. Base44 AI operates under a SaaS model accessible at base44.ai, and its generated sites tend to follow a predictable structural template that makes it one of the more straightforward AI builders to detect programmatically once the fingerprint pattern set is established.
Bubble
Bubble is a no-code and AI-assisted full-stack application development platform used by entrepreneurs, startups, and non-technical founders to build web applications without writing traditional code. Our detection engine identifies Bubble-powered sites using a combination of 2 script patterns, 2 HTML patterns, and 1 HTTP header, giving it a well-rounded fingerprint across multiple layers of a page's technical stack. Script patterns typically involve Bubble's proprietary runtime JavaScript loaded from their CDN infrastructure, while HTML patterns reflect Bubble-specific markup attributes and structural elements injected into the rendered DOM. The HTTP header signal further distinguishes Bubble deployments at the network response level, making it detectable even when frontend code is partially obfuscated or customized. Bubble applications are hosted on Bubble's own cloud infrastructure by default, with custom domains available on paid plans, and this consistent hosting environment contributes to reliable, high-confidence detection across the wide variety of app types — from marketplaces to SaaS dashboards — that its users build on the platform.
