Flask Website Examples
Flask is a minimalist Python web framework popular for prototypes, internal APIs, and small-to-medium applications where developers want full control without a large framework's conventions imposed on them. Flask has no distinctive markup or cookie signature by default, so AIWebsiteDetector relies on the `Werkzeug` banner Flask's built-in development server sends in its `Server` response header — a strong signal when present, but one that's typically absent once a Flask app is deployed behind a production WSGI server like gunicorn, so Flask is more reliably detected on demos and prototypes than on hardened production deployments.
