Domain Expiry Monitor

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.

Domain Expiry Checker

datapilot/domain-expiry-checker

It extracts registrar, expiry date, status, name servers, and days left. Flags expiring domains (critical/warning) and outputs structured JSON—ideal for domain monitoring, SEO audits, and portfolio management. 🌐📅

Bulk Domain Checker

kawsar/bulk-domain-checker

Bulk domain checker that extracts domain availability status across 80+ extensions so you can find unregistered names fast. A powerful domain finder tool that helps you secure the best domain for your business or personal website.

Domain Inspector

visita/domain-inspector

A powerful, all-in-one tool to perform DNS lookups, WHOIS queries, HTTP status checks, and SSL certificate validation for a list of domains. It can clean full URLs down to the bare domain (e.g., https://www.apify.com/store → apify.com) and run all checks in a single batch.

Track domain expiry, registrar, statuses and nameservers via RDAP (modern WHOIS). Get days-until-expiry alerts. Schedule-ready.

Reports public RDAP, TLS certificate, MTA-STS, DMARC RUA, and security.txt deadline signals for bare domains.

Domain Expiry & SSL Certificate Monitor - DNS Change Alerts

that_red_bird/domain-ssl-monitor

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

Monitoring Checker Duplication

apify/monitoring-checker-duplication

The Monitoring checker duplication is a part of the Apify Monitoring Suite (apify/monitoring). See its readme for more information and how to use this.

Look up many domains at once over RDAP, the official successor of WHOIS: expiry, creation and update dates, registrar, nameservers, status codes and DNSSEC. No registrant or contact data. Unregistered and failed lookups are free.
