How it works

Three steps.
None of them are hard.

01
Tell us, or your agent
Describe the project. Type it here, or do it inside Claude or ChatGPT — same answer either way.
02
Pick a name you like
We check 23 endings at once. Available ones cost what they cost — never a “premium” markup.
03
It's yours, set up
WHOIS privacy on. Auto-renew on. DNS pointed wherever you ask. We don't hide any of it.

Everything included

One price. Five things. No upsells.

Other registrars charge for privacy and bundle add-ons you didn't ask for. We don't. The price you see is the whole price.

From a builder
“I was on a call with Claude. Said ‘grab me clearbrew.com.’ It came back with the receipt before we kept talking.
That's the whole experience I want.”

Questions

What people ask before they buy.

Is this a real registrar or a reseller?+
A reseller — we partner with ICANN-accredited registrars and the registry sees your registration the same way it would going direct. You can transfer out to any other registrar at any time, free.
What happens if I let an AI buy a domain for me?+
Same as buying it yourself. The agent uses an authenticated key you grant — scoped to a budget you set. Revoke anytime.
Can I move a domain I already own to Just?+
Yes. Inbound transfers are free. We pay the renewal year you bring with you. Outbound transfers are also free, no questions.
What if the price changes at renewal?+
It does — wholesale prices change at the registry level. We pass them through unchanged. We never mark up. You'll get a heads-up before any renewal.
Why no hosting / no website builder / no email plans?+
Because someone else does each of those better. Just registers domains. Use whoever you want for the rest.
