Express.js Website Examples
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.
