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.
Cloudflare CDN
Cloudflare CDN is a globally distributed content delivery network used by millions of websites — from small personal projects to large-scale enterprise platforms — to accelerate performance, improve reliability, and mitigate DDoS threats by routing traffic through Cloudflare's edge infrastructure. As one of the most widely deployed CDNs on the internet, it appears across virtually every category of website, making accurate detection both highly relevant and technically straightforward. AIWebsiteDetector.com identifies Cloudflare CDN deployments by analyzing 2 distinct HTTP response headers that Cloudflare consistently injects into traffic passing through its network, providing a reliable and precise fingerprint for detection. These headers are characteristic of Cloudflare's edge servers and remain present regardless of the underlying origin technology or CMS, which contributes to high detection confidence across diverse site types. Cloudflare CDN is available as part of Cloudflare's broader platform, with a free tier accessible to all users and paid plans unlocking advanced performance and security features — making it one of the few enterprise-grade CDN solutions with significant adoption at the hobbyist and small business level. More details about Cloudflare's CDN offering can be found at the official product page: https://www.cloudflare.com/cdn.
