About DomainDetails

What is DomainDetails?

DomainDetails is a private, local-first domain lookup tool that combines WHOIS, RDAP, DNS, SSL, Wayback history, TLD availability, and marketplace price comparison in one interface. It solves the problem of scattered domain research and missed opportunities on expiring or changing domains.

Who is it for?

Startup founders, domain investors, indie hackers, brand protection teams, SEO professionals, and agencies. It's not for casual users who only need a one-off WHOIS check and don't need monitoring or alerts.

Real use cases

Monitor a parked domain you want for your startup name and get notified within minutes of ownership change. Watch for expiring backlink-rich domains for SEO. Track aftermarket price drops on your shortlist. Catch typo-squatters early for UDRP filings. Keep an eye on client domains for DNS or expiry issues before they become problems.

Key features

  • Unlimited WHOIS/RDAP lookups — Get detailed domain records instantly, no account required.
  • DNS, SSL, and Wayback checks — See historical DNS, SSL certificates, and website snapshots.
  • TLD availability checker — Find available domains across 1,500+ TLDs.
  • Marketplace price comparison — See aftermarket prices from Afternic, Sedo, Namecheap, Seller Hub, Dynadot, Atom, NameSilo, and Unstoppable Domains.
  • Domain Alerts — Get email alerts within minutes of WHOIS, DNS, ownership, expiry, or marketplace changes (first watched domain free).
  • 90-day change history — Review visual diffs of every change to watched domains.
  • Cross-device sync — Your watchlist follows you across desktop, mobile, and tablet.
