Platform Overviews
Bolt
Bolt is an AI-powered website and application builder developed by StackBlitz, primarily used by developers and technical users who want to rapidly prototype and deploy full-stack web applications directly from natural language prompts. The platform generates production-ready code in the browser, making it a distinctive target for detection due to its tight integration with StackBlitz's runtime infrastructure. AIWebsiteDetector's detection engine identifies Bolt-built sites through a combination of 3 script patterns, 3 HTML patterns, and 2 meta tag patterns embedded in the page markup, alongside 2 CDN domains that consistently appear in asset delivery and 2 HTTP response headers that expose the underlying platform. These signals work in combination to produce reliable detections across a range of project types, from single-page applications to more complex full-stack deployments. Bolt sites are characteristically hosted within the bolt.new ecosystem or exported to connected deployment targets, and the platform's deep reliance on WebContainer technology leaves consistent, identifiable fingerprints across both the DOM structure and network layer that distinguish it cleanly from other AI website builders.
Durable
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.
Key Differences
- Both Bolt and Durable are classified as AI Website Builder tools, making them the most direct competitors in this comparison.
- Bolt scores higher on AI involvement (90/100 vs 90/100 for Durable), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies Bolt using 12 fingerprint patterns and Durable using 14 patterns — more signals generally means more reliable detection.
- Bolt serves assets from
/bolt\.host/iwhile Durable uses/cdn\.durable\.co/i— making CDN domain analysis one of the most reliable ways to distinguish them.
