What You Can Do

Domain Age Checker — Find out exactly when a domain was registered, who the registrar is, when it expires, and how many years it has been active. Domain age is a factor in search engine trust, domain valuation, and buyer due diligence. Our age checker uses RDAP, the modern replacement for traditional WHOIS, to pull accurate registration data from authoritative sources.

DNS Lookup Tool — Query a domain’s DNS records in real time: A, AAAA, MX, NS, TXT, CNAME, and SOA records via Cloudflare’s DNS-over-HTTPS resolver. Essential for troubleshooting email delivery, verifying hosting configuration, and auditing DNS security.

SSL Certificate Checker — Verify whether a domain has a valid SSL/TLS certificate and is accessible over HTTPS. Since 2018, Google Chrome marks all HTTP sites as “Not Secure” and HTTPS is a confirmed ranking signal. Our checker tests live connectivity and reports a pass/fail grade. For more context, read our guide on free vs paid SSL certificates.

Domain Availability Checker — Check whether a domain name is available across .com, .net, .io, .ai, .dev, and 7 more TLDs. Useful for brand research, startup naming, and domain investing. Not sure which extension to pick? Our guide on choosing the best TLD breaks it down.

Domain Reputation Checker — Run a four-point reputation scan covering HTTPS status, DNS configuration, email authentication (SPF and DMARC), and domain age assessment. Ideal for evaluating domains before purchase or for checking if a domain is blacklisted.
