🔐 Domain, SSL & DNS Monitor - Expiry + Change Alerts

that_red_bird/domain-ssl-monitor

⚡ Never lose a domain or serve an expired certificate again. ✅ Domain expiry via RDAP, live TLS certificate expiry and validity, nameserver and DNS record changes. ✅ Warns before expiry and alerts the moment records move. No API key needed.

Find a domain's subdomains from Certificate Transparency logs, resolve each to its IP, and check the live SSL certificate (issuer, expiry, days left). Open-source recon, no API key.

Monitor domain registration and SSL certificate expiry across every site you own or manage. Days remaining, registrar, certificate issuer, trust problems and an alert level per domain, in one dataset.
