Platform Overviews
BunnyCDN
BunnyCDN is a content delivery network and hosting platform developed by bunny.net, designed for developers, media publishers, and businesses seeking fast, cost-effective global asset delivery with edge storage capabilities. The detection engine on AIWebsiteDetector.com identifies BunnyCDN-powered sites through a combination of two distinct CDN domain patterns — typically subdomains or URLs routed through BunnyCDN's edge network — alongside one characteristic HTTP response header that BunnyCDN injects during content delivery. These signals are parsed from live HTTP responses and network requests, allowing the detector to distinguish BunnyCDN from other CDN providers with high specificity. BunnyCDN is particularly recognizable due to its use of the `b-cdn.net` domain family for pull zones and storage zones, which appear consistently across asset URLs embedded in page markup and scripts. This combination of domain fingerprinting and header analysis makes BunnyCDN one of the more reliably detectable CDN platforms, as its network routing leaves persistent, identifiable traces at the HTTP layer rather than relying solely on JavaScript-side signals.
Fastly
Fastly is a high-performance edge cloud platform and content delivery network used primarily by enterprises, media companies, and high-traffic web applications that require low-latency content delivery, real-time streaming, and programmable infrastructure at scale. The platform is widely adopted by technology companies, news publishers, and e-commerce operators that demand granular control over caching and request routing at the network edge. AIWebsiteDetector.com identifies Fastly deployments by analyzing 2 distinct HTTP response headers that Fastly injects into served traffic, providing reliable, server-side signals that remain consistent across the wide variety of site types and configurations built on the platform. These header-based signals make Fastly particularly straightforward to detect programmatically, as they appear regardless of front-end framework or CMS in use, meaning the underlying CDN layer is exposed even when the application stack is otherwise obscured. Fastly operates on a usage-based pricing model with no upfront commitments, positioning it as a premium infrastructure choice that distinguishes it from shared or budget hosting environments — a characteristic that often correlates with high-traffic, performance-critical deployments in detection results.
Key Differences
- Both BunnyCDN and Fastly are classified as CDN tools, making them the most direct competitors in this comparison.
- BunnyCDN scores higher on AI involvement (10/100 vs 10/100 for Fastly), meaning it relies more heavily on AI for site generation and content creation.
- Our detection engine identifies BunnyCDN using 3 fingerprint patterns and Fastly using 2 patterns — more signals generally means more reliable detection.
