How Our Beaver Builder Detector Works
When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 3 Beaver Builder-specific fingerprints:
Script analysis
We scan all loaded JavaScript files for known CDN paths and runtime names
CDN domain matching
We cross-reference every asset request against known platform CDNs
HTML pattern scanning
We search the DOM for platform-specific class names and data attributes
Header inspection
We read HTTP response headers that identify the server or platform
Meta tag extraction
We check generator and other meta tags in the document head
Confidence scoring
We weight each matched signal and normalize to a 0–99% score
