Substack Stack Detection

Official Website

Newsletter subscription and independent publishing network.

Detection Heuristics & Signature Markers

Our engine inspects multiple observable layers to identify Substack with verified confidence:

Script Bundle Paths: Analyzes script src attributes for Substack runtime chunks and vendor libraries.

Evidence Limitations & Security Hardening

Production websites frequently implement security hardening to suppress response headers (like Server or X-Powered-By) or minify script bundles. While this may reduce confidence to Medium or require deep DOM inspection, it does not prevent our multi-vector engine from identifying underlying patterns.
