Domain Checker — WHOIS, DNS, SSL & Expiry Dates in Bulk

Check many domains at once: who the registrar is, when the domain was registered and when it expires, its status and name servers; its DNS records with SPF and DMARC; its SSL certificate — issuer, expiry, days left, trusted or not; and where the website ends up after redirects. One row per domain.

Why this one

• 📅 Expiry dates you can act on. Domain expiry and SSL expiry, with days left, for every domain — ready for a renewal reminder.
• 🧾 Straight from the registries. Registration data comes from each registry's official RDAP service (1,202 TLDs, found through IANA's directory). Subdomains are checked against their registered parent.
• ✉️ Email set-up at a glance. MX, SPF and DMARC with its policy (none / quarantine / reject).
• 🔒 SSL problems spelled out. Expired, self-signed or untrusted certificates are reported with the reason.
• ⚡ Fast. 20 domains in 5 seconds in a live test run.
• 🧑‍⚖️ No personal data. Registrant names, emails and phone numbers are never read or delivered — only registrar, dates, status and name servers.

2. Keep the checks you need: Registration, DNS records, SSL certificate, Website.
3. Press Start, and download the results from the Output tab as JSON, CSV or Excel.

To watch expiry dates, save your list as a task and schedule it weekly, then filter on daysToExpiry and sslDaysLeft.

You can also call it from the Apify API, from Make, Zapier or n8n, or from an AI agent through the Apify MCP server.

FAQ

Why is registration data missing for some domains? Some country registries — .de and .hu among them — offer no RDAP service, and their older WHOIS services restrict automated use. Those domains get DNS, SSL and website data, and registrationUnavailable says why.

Does it show who owns a domain? No. Owner contact details are personal data and are mostly hidden by registries anyway.
