Domain tools
Nine tools, no account, no signup. Six query our registry partner for live availability and pricing; three use the public RDAP and DNS protocols directly.
Which one you want
Most visits start in one of three places. If you have a name in mind and want to know whether you can have it, use the domain search, or the bulk check when there are more than a handful. If you do not have a name yet, the domain name generator works from a keyword and returns only names that are actually free, which is the difference between a suggestion tool and a list of things somebody else already owns. And if you are working out what a name will cost you over the years you intend to hold it, the multi-year price calculator answers that, because the first-year figure almost never does.
The rest answer questions about a name that already exists: who holds it, when it expires, and what its DNS is doing. Those are the ones you reach for when something has gone wrong rather than when you are buying.
All domain tools
Domain Availability Check
Type any name and see instantly whether it is available, what it costs to register, and — the number most registrars hide — what it costs to renew.
Bulk Domain Availability Check
Paste a list, get a sortable table with pricing and a CSV export. Built for portfolio owners, brand protection, and anyone who has ever checked names one at a time.
Check a Name Across Every Extension
Enter a name once and see where it is free across the extensions that matter, with prices attached.
Domain Name Generator
Give it a word. It returns available names built around that word, priced, across a range of extensions.
Multi-Year Domain Price Calculator
See the total and the effective annual rate for every term from one year to ten, so a long registration is a decision rather than a guess.
WHOIS & RDAP Domain Owner Lookup
Registrar of record, registration and expiry dates, status codes, nameservers, and DNSSEC status — pulled live from RDAP, the protocol that replaced WHOIS.
Domain Expiration Date Checker
The expiry date, the days remaining, and — the part that matters — exactly where the domain sits in its lifecycle and what happens next.
DNS Record Lookup
A, AAAA, MX, TXT, NS, SOA, and CAA records with their TTLs, queried live over DNS-over-HTTPS.
Why some of these do not use our registry partner
The WHOIS, expiry, and DNS tools query public internet protocols rather than a commercial API. RDAP is the ICANN-mandated registration data protocol; DNS-over-HTTPS is the standard resolver interface. Both are open, free, and authoritative for what they report — and neither requires you to be our customer.
