Describe what you're building. The AI suggests brandable names and checks each one against the registry as it goes, so the list only shows domains you can register right now. Free, no signup, 11 extensions.
Want to know what a name is worth? Domain value calculator.
One sentence on what you are building and who it is for. Tick the extensions to check (.com unless you add others) and how many available names you want.
Each name the AI suggests is looked up in the registry's RDAP record as it streams in. Taken names drop out, and it keeps drafting new rounds until it reaches your count.
Ask for shorter names or a different tone in the same thread, or hit Register: the domain goes in your name with free WHOIS privacy, and your card is only charged if registration succeeds.
Four sample briefs, each with three names that were unregistered when we checked them on October 25, 2026. Good names get taken, so run a brief to get a fresh list of your own.
75% of the .com names people checked on domhaul were already registered. On .io it was 36% and on .app 37%, so ticking a second extension usually turns up more open names than rewording the brief.
| Extension | Names checked | Already registered | Share |
|---|---|---|---|
| .com | 4,260 | 75% | |
| .org | 39 | 67% | |
| .dev | 55 | 55% | |
| .co | 202 | 54% | |
| .ai | 271 | 48% | |
| .net | 72 | 46% | |
| .si | 402 | 44% | |
| .app | 399 | 37% | |
| .io | 77 | 36% |
Distinct names looked up on domhaul (the site and its AI assistant tools) from August 4, 2026 to October 24, 2026, extensions with 5 or more checks. .xyz has too few checks to show; .ch is left out because nearly all of its checks came from one automated brainstorming run.
Lowest first-year price per year at Dynadot or Porkbun on October 24, 2026. Renewals often cost more; each page has register, renew and transfer prices.
Grabbing the name is step one. Here's how to turn it into a real presence.
Good available names don't last. Hit Register on any available result and domhaul registers it in your name, with free WHOIS privacy. Your card is only charged if registration succeeds.
A name@yourdomain.com address looks far more legit than a free inbox. Captain domhaul members get one-click mailboxes from the dashboard, with no separate provider to wire up.
Grab the matching handles on X, Instagram, and TikTok before someone else does, and consider the .io or .co variant so no one can ride on your name. Check which handles are still free.
Even a one-page landing site or a 'coming soon' page starts building SEO and lets people find you while you build.

Describe what you're building in plain English and domhaul's AI generates brandable name ideas, then checks each one for availability across .com, .io, .app and other TLDs in real time. You only see names you can actually register.
Eleven: .com, .io, .dev, .app, .co, .net, .org, .ai, .xyz, .si and .ch. It checks .com unless you tick others. With several ticked, a name counts as available when any of them is open, or turn on "Require all selected domain types available" to keep only names that are open on every one.
Namelix is a brand name generator: it is good at short invented names and shows logo mockups, and the domain is a separate step. domhaul starts from the domain. Every suggestion is checked against the registry for the extensions you pick, taken names are filtered out before you see them, and you can register the one you like at the standard price on the same page.
No signup is needed to generate or check names. Every name shown as available was looked up in the registry at the moment of your search; only taken results are cached, never available ones. Someone else can still register a name after you see it, so if one is right, register it promptly. Your card is only charged if the registration goes through.
Searching is free. Generate ideas and check availability as much as you want. We make money from ads, from referral links when you register a domain elsewhere, and from a small service fee when you buy a domain directly through domhaul.
Yes. Type the exact name into the search and domhaul will check that domain across every supported extension instead of generating new ideas.
Right here. Click Register on any available result and domhaul registers the domain in your name, with free WHOIS privacy, through Stripe checkout. Your card is only charged if registration succeeds. From then on you manage DNS and nameservers from your domhaul dashboard, and you can transfer the domain out to your own registrar account whenever you want. Mailboxes on your domain are part of the Captain plan.
Short, easy to spell, easy to say out loud, and ideally a .com. Avoid hyphens and numbers. If the perfect .com is gone, a clean .io, .app, or .co is a solid alternative for many projects.
