Relume is an AI-powered website builder and component library platform primarily used by web designers and Webflow developers to rapidly scaffold and prototype site layouts using pre-built, customizable UI blocks. AIWebsiteDetector.com identifies Relume-built or Relume-assisted sites through a combination of five distinct technical signals: two JavaScript script patterns embedded in page source, one proprietary CDN domain used to serve Relume's component assets, and two characteristic HTML patterns that reflect the platform's structured component markup conventions. These signals are cross-referenced by the detection engine to establish confidence, as Relume's tight integration with Webflow means its fingerprints often appear alongside Webflow-specific attributes, making precise pattern matching critical to avoid false positives. Relume is notable for its hybrid positioning — functioning less as a standalone hosting platform and more as a design-layer tool that outputs into Webflow or similar environments, which gives its detection profile a distinctive character compared to self-contained builders like Framer or Webflow alone. Its official presence at relume.io reflects its focus on the designer and agency market, where teams use it to accelerate production workflows rather than deploy finished sites directly.
