AI Coding Tool
Cloudflare CDN
CDNNext.js and Cloudflare CDN are both popular choices, but they serve different needs. Next.js is a AI Coding Tool with a traditional, manual approach to building, while Cloudflare CDN is a CDN that prioritises developer or designer control.
Below you'll find a side-by-side breakdown of detection signals, AI scores, and technical fingerprints — plus our honest take on which builder wins for different use cases.

AI Coding Tool
Next.js is a ai coding tool with an AI Score of 65/100 (AI-Assisted). Our detection engine uses 5 signal patterns to identify Next.js-built sites.
CDN
Cloudflare CDN is a cdn with an AI Score of 10/100 (Unknown). Our detection engine uses 2 signal patterns to identify Cloudflare CDN-built sites.
Next.js is a React-based web framework developed by Vercel, widely adopted by developers and engineering teams building production-grade web applications that require server-side rendering, static site generation, or hybrid routing architectures. AIWebsiteDetector.com identifies Next.js deployments through a combination of 2 script patterns, 2 HTML patterns, and 1 HTTP header — a multi-signal approach that yields reliable identification even when sites are deployed behind CDNs or custom domains. Common detection markers include inline script references to Next.js chunk files, characteristic `__NEXT_DATA__` JSON blocks embedded in page HTML, and the `x-powered-by: Next.js` HTTP response header present on many default deployments. The HTML-level patterns are particularly robust, as the `__NEXT_DATA__` script tag is injected server-side and persists across most configurations unless explicitly suppressed. Next.js sites are most frequently hosted on Vercel's infrastructure, though deployments on AWS, Netlify, and self-hosted Node.js servers are common — making header-based signals less universally reliable than the DOM and script pattern checks. The framework's official documentation and resources can be found at [nextjs.org](https://nextjs.org).
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.
