How was this detected?
For spline.design, DetectZeStack identified 4 technologies: 3 via HTTP fingerprinting and 1 via TLS handshake.
Detection runs four independent layers in parallel: HTTP response headers, TLS handshake metadata, certificate issuer inspection, and DNS record lookups. The breakdown above shows which layers fired for this specific domain — some sites carry most of their fingerprint in HTTP, others rely heavily on infrastructure (DNS/TLS).
