Platform Overviews
Express.js
Express.js is a minimal, unopinionated Node.js web framework used across the JavaScript ecosystem as the default choice for REST APIs, server-rendered apps, and the backend layer under countless full-stack projects (including many AI-generated ones, since Node/Express is a natural pairing for a JS-generated frontend). AIWebsiteDetector identifies Express deployments through the `X-Powered-By: Express` response header, which Express sets by default on every response unless a developer explicitly disables it via `app.disable('x-powered-by')` — a single reliable header is normally enough for confident detection.
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.
