Durable is an AI-powered website builder designed primarily for small business owners and freelancers who need to generate a functional, branded website in seconds without technical expertise. Our detection engine identifies Durable-built sites through a combination of 3 distinct script patterns, 3 CDN domains, 4 HTML patterns, 3 HTTP headers, and 1 meta tag pattern, providing a multi-layered fingerprint that makes accurate identification reliable across a wide range of deployments. The HTML patterns and meta tag signals are particularly consistent across Durable sites, reflecting the platform's templated output architecture where generated markup follows predictable structural conventions. Script references and CDN domain usage tied to Durable's infrastructure further reinforce detections, especially when header-level signals confirm the underlying hosting environment. Durable hosts all sites on its own managed infrastructure at durable.co, meaning sites rarely appear on third-party hosting providers — a characteristic that strengthens detection confidence since the platform's fingerprints are tightly controlled and seldom mimicked by other builders.
