AI App Builder
WordPress
CMSBubble and WordPress are both popular choices, but they serve different needs. Bubble is a AI App Builder with heavy AI involvement in the build process, while WordPress is a CMS that prioritises developer or designer control.
Below you'll find a side-by-side breakdown of detection signals, AI scores, and technical fingerprints — plus our honest take on which builder wins for different use cases.

AI App Builder
Bubble is a ai app builder with an AI Score of 75/100 (AI-Assisted). Our detection engine uses 5 signal patterns to identify Bubble-built sites.
CMS
WordPress is a cms with an AI Score of 20/100 (Traditional). Our detection engine uses 11 signal patterns to identify WordPress-built sites.
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.
WordPress is an open-source content management system powering everything from personal blogs to large-scale enterprise websites, making it the most widely deployed CMS on the web and a primary target for accurate fingerprinting. AIWebsiteDetector.com identifies WordPress installations using a layered set of technical signals, including 3 distinct script patterns, 2 HTML structural patterns, 2 HTTP response headers, 2 meta tag patterns, and 1 CDN domain reference — collectively providing high-confidence detection across both default and heavily customized deployments. These signals typically manifest as characteristic markup in page source, identifiable request headers returned by the server, and script references tied to WordPress core or its content delivery infrastructure. Because WordPress supports thousands of themes and plugins that can obscure surface-level indicators, the multi-signal approach ensures reliable identification even when administrators attempt to minimize the platform's visible footprint. WordPress itself is free and open-source, but hosting costs vary widely — from shared environments to managed WordPress hosting — meaning the same CMS signature can appear across dramatically different infrastructure setups, a nuance the detection engine accounts for when evaluating header and CDN patterns.
