Domain Checker: DNS, SSL and Registration

WHOIS Domain Lookup — Registrar, Age, Expiry & DNS (Bulk)

ntriqpro/whois-domain-lookup

Look up WHOIS records for hundreds of domains in a single run: registrar, creation and expiry dates, domain age, days until expiry, nameservers, DNSSEC and status codes. Public registry data for every major TLD (.com, .org, .io, .co.uk and more) — no API keys, structured JSON/CSV output.

Monitor WHOIS/RDAP, SSL certificates (crt.sh), and DNS records for domains. Detects changes (registrar change, DNS hijacking, SSL expiry) and alerts via webhook. Pay-per-event, no rental.
