Carrd is a lightweight, single-page website builder popular among freelancers, creators, and developers who need simple portfolio, landing, or link-in-bio pages deployed quickly without complex tooling. AIWebsiteDetector.com identifies Carrd-powered sites through a combination of one script pattern, one HTML pattern, and one meta tag pattern embedded in the page source — signals that remain consistent across Carrd's hosted infrastructure regardless of custom domain configuration. The script pattern typically references Carrd's own asset delivery network, while the HTML and meta tag patterns reflect structural and namespace conventions that Carrd injects into every published page by default. These three detection signals work in concert to produce reliable identification even when site owners apply custom branding or remove visible Carrd attribution. Carrd operates on a freemium model, with free plans hosting sites under carrd.co subdomains and paid Pro tiers enabling custom domains — a distinction that makes subdomain-based detection straightforward, while the script and markup fingerprints ensure confident detection extends to customized deployments as well.
