Domain availability checker

Check one name on .com, .co, .io, .ai and .net against the registries' own records.

One word, no ending. We check .com, .co, .io, .ai and .net.

What this checks

Four things this check gives you.

01

Five endings at once

One name, checked on .com, .co, .io, .ai and .net together, so you can see the whole picture before you pick.

02

The registry's own record

We read RDAP, the lookup service the registries publish themselves. It is the same source a registrar reads when it tells you a name is free.

03

No cart and no upsell

We show what the registry says and stop. No purchase links, no affiliate tags, no alternative names you did not ask for.

04

What a free answer means

No registration on record. A name can still be reserved, held back by the registry or priced as a premium, so a registrar has the last word.

What to do next

Clear the name, then lock it down.

A free name is the first step of four. These are the ones that save money later.

  1. 01

    Check the name is free to use as well as to buy

    Search the business register where you will trade and the trademark office for the same words. A free domain with someone else's trademark on it is a letter waiting to arrive.

  2. 02

    Pick the ending your buyers expect

    People type .com by default, so a .com you have to explain costs you traffic every month. The other endings work when the name reads as a whole word with the ending, or when your buyers already live in that corner of the web.

  3. 03

    Register it at a registrar and lock it

    Any registrar can take the name. Once it is yours, turn on auto renew, turn on the registry transfer lock, and put the renewal on a card that does not expire before the domain does.

  4. 04

    Set the mail records up before you send anything

    A brand new domain has no sending history, so these checks matter even more. Publish SPF, DKIM and DMARC on day one and send slowly for the first few weeks.

    v=spf1 include:_spf.google.com -all
    v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com

Questions

The things people ask next.

What does likely free mean?+

The registry has no registration on record for that name. That is the same source a registrar reads, so it is a good answer, though only a registrar can promise it. A name can be reserved, blocked by the registry or priced as a premium, and only the registrar's checkout settles it.

What is RDAP?+

The registries' own lookup service, the one built to replace WHOIS. It answers in a plain data format with who holds a domain and when it was registered, and every registry that runs one publishes it openly.

Why are some endings answered differently?+

Not every ending has an RDAP service in the public directory. For those we fall back to DNS: a name with name servers on it is registered, and a name with none we leave open rather than guess at it.

Does checking a name here put it at risk?+

No. The check is a read of a public record and nothing about it is stored on our side. If you are worried about a name being taken while you think it over, the only real answer is to register it once you have decided.

The same work, every client

Your AI can run this and 800+ more checksfor every client.

The name and domain power takes a business idea, works up names, checks the endings and the trading name behind them, and hands back a shortlist you can act on.
