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.
Lovable
Lovable is an AI-powered web application builder targeted at founders, product teams, and non-technical creators who want to generate and deploy full-stack web apps through natural language prompts. Sites built with Lovable carry a distinctive technical fingerprint that AIWebsiteDetector.com's engine identifies through a combination of 5 script patterns, 4 CDN domains, 8 HTML patterns, 3 HTTP headers, and 3 meta tag patterns — making it one of the more richly signaled AI builders in our detection database. Key detection signals include characteristic HTML attributes and structural markup injected at build time, alongside CDN domain references and HTTP response headers that persist even when sites use custom domains. Script loading patterns tied to Lovable's runtime infrastructure provide particularly reliable indicators, as these are difficult to strip or obfuscate without breaking core application functionality. Lovable projects are typically hosted on Lovable's own infrastructure by default, with the option to connect custom domains — a deployment pattern that contributes to the consistency and high confidence of detections across the sites we scan.
