Registry records (RDAP)
Registration, expiry and status data is read live from the registry of each extension through RDAP, the protocol that replaces WHOIS. It is the same record registrars see.
Free domain tools, straight from the registry.
Seven small tools for the questions you ask before buying a domain: how old it is, when it expires, when it will drop, who the registrar is, how strong its backlinks are and whether it is free to register. No sign-up, no ads.

Free tools: frequently asked questions
Are these domain tools really free?
Yes. All seven tools work without an account and without a card. The bulk tools accept 5 domains at a time as a guest, 20 with a free account and 50 on Hunter Pro. The only paid tool on the site is the full domain report, which reads the archive history and backlinks.
Which extensions are supported?
Every extension whose registry publishes RDAP: .com, .net, .org, .info, .io, .co, .ai, .dev, .app, .xyz, .uk, .fr, .nl and more than a thousand extensions in total. A few registries do not offer RDAP (for example .se, .nu, .it, .es and .com.tr); for those the tools say so instead of guessing.
Do you store the domains I look up?
No list of your lookups is kept. Registry answers are cached for a few minutes so that repeating the same query does not hit the registry again, and Domain Rating values are cached for a week.
What is the difference between these tools and the domain checker?
The free tools answer one factual question each from registry and DNS data. The domain checker is a full due-diligence report on one domain: Wayback history, spam periods, blacklists, Trust Flow, referring domains and anchor texts, scored from 0 to 100.
