Frequently asked questions
Is the Domain Inspector free?
Yes — it's completely free, with no signups, accounts or rate limits.
Where does the WHOIS data come from?
We query the authoritative RDAP server for each TLD (e.g. Verisign for .com, Identity Digital for .dev) to return registrar, creation, expiry and update timestamps.
Can I check SSL expiry with this tool?
Yes. The SSL panel shows the certificate issuer, valid-from / valid-to dates and the number of days remaining.
Which DNS records does it return?
It returns A, AAAA, MX, TXT, NS and CNAME records via Cloudflare's DNS-over-HTTPS resolver.
