How it works inside

The tool does not send HTML to third-party fingerprint providers.

Low-confidence detections require manual review.

05

Questions and answers

Why are not all technologies detected?

Because the tool does not execute JavaScript or analyze runtime network waterfalls. That belongs to a separate browser/crawler layer.

Can the result be used for security conclusions?

Only as context. Security conclusions require dedicated header, TLS, exposed-version, and configuration checks.
