Ever wonder what SSL certificates are behind all the requests a webpage makes? Cert Inspector captures the full network footprint via a headless browser and shows you every certificate and DNS record. Great for security audits and debugging.

Copilot says: AI-generated

Point it at any webpage and watch it spider through every single domain that gets loaded — ads, trackers, APIs, the works — showing you SSL certificate health, DNS records, and which certs are about to expire before they ruin your day.

Key features:

  • 🕷️ Playwright-powered deep inspection captures the full request tree including JS-loaded resources
  • 🚦 Color-coded health dashboard shows expired, expiring, and healthy certs at a glance
  • 📅 Timeline view visualizes when certificates expire so you can plan ahead
  • 📦 Download-and-run executables for Windows, Mac, and Linux with zero dependencies
