Platform Overviews
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.
Softr
Softr is a no-code platform that enables non-technical users, startups, and internal teams to build web applications, client portals, and membership sites on top of data sources like Airtable and Google Sheets. AIWebsiteDetector.com identifies Softr-powered sites through a combination of six distinct technical signals, including two JavaScript script patterns embedded in page markup, one CDN domain consistently loaded by Softr deployments, two characteristic HTML patterns present in the rendered DOM, and one meta tag pattern that exposes the platform fingerprint in the document head. These signals collectively allow the detection engine to distinguish Softr sites with high confidence, even when publishers have applied custom domains or branding that obscures the underlying platform. Softr sites are typically hosted on Softr's own infrastructure with custom domain mapping available across paid tiers, while free-tier deployments often retain a recognizable subdomain structure that serves as an additional corroborating indicator during automated scans.
