Domain Portfolio & Expiry Monitor

Watch your domains for approaching expiry, registrar transfers, nameserver changes and status flags. Uses open RDAP data, so there are no API keys and no rate-limit setup.

WHOIS & DNS Enrichment

cynix_dev/whois-enrichment

Enrich domains with structured WHOIS data (registrar, registration/expiration dates, status, nameservers) and optional DNS records (A, AAAA, MX, NS, TXT) via free public RDAP and DNS-over-HTTPS. No API key required. Great for lead enrichment, domain due-diligence, and security triage.

Domain Trust Reputation Scraper

taroyamada/domain-trust-monitor

Audit your entire domain portfolio for SSL expiry, DMARC posture, and security headers, outputting an executive summary with clear remediation rows.

Bulk WHOIS Lookup: Domain Age, Expiry, Registrar

thoob/rdap-domain-lookup

Looks up domain registration data through official IANA RDAP servers (the structured-JSON successor to WHOIS): registrar, key dates, status codes, nameservers, DNSSEC, and abuse contact. Clean fields, no mangled WHOIS text. Billed only per resolved domain.

RDAP Domain Expiry & Whois Scraper

taroyamada/rdap-domain-monitor

Track domain expirations and ownership changes via RDAP to catch dropped URLs, monitor competitor assets, and protect your organic search equity.

Bulk domain intelligence: registrar, age and expiry via official RDAP (structured WHOIS), SSL certificate expiry and trust, DNS records (A/AAAA/MX/NS/TXT), plus clear warnings like "expires in 30 days". Registrant contact details are never extracted - registry facts only.

SSL Certificate Expiry Monitor

andok/ssl-certificate-monitor

Monitor SSL/TLS certificate validity and expiration dates across thousands of domains to prevent costly outages.

Monitor SSL certificates for expiry, chain validity, and cipher suites. Discover subdomains via Certificate Transparency logs (crt.sh). Alerts for certificates expiring within N days. No API key required.

SSL & Domain Expiry Monitor - Certificate + RDAP Checks

lowlanddata/ssl-domain-monitor

Certificate expiry and domain-registration expiry for a list of hosts, one row each, with a plain list of what is wrong. A real TLS handshake and RDAP - no third-party checking API, no rate limit.

WHOIS / RDAP Domain Scraper & Change Monitor

automa-flow/domain-rdap-change-monitor

Run bulk WHOIS/RDAP domain lookups and monitor expiry, renewals, registrar transfers, nameservers, DNSSEC, DNS and SSL/TLS certificates. Get authoritative registry data, exact change events, safe NOT_FOUND confirmation and no registrant PII.

Bulk SSL/TLS certificate checker API for expiry monitoring, HTTPS audits, issuer/SAN extraction, chain validation, TLS version, and cipher-suite evidence. Scan domains for expiring, expired, or misconfigured certificates before outages or compliance reviews.
