NetSense CT is an open-source, real-time Certificate Transparency monitor. It streams newly issued TLS certificates from 27 global CT logs (Google, Cloudflare, DigiCert, Sectigo, TrustAsia), extracts every domain name, flags certificates belonging to 18 major AI companies, and offers full-text domain search plus watch alerts.
This app requires JavaScript for the live stream. The REST API works without it: OpenAPI 3.1 documentation, live statistics, domain search.
