Real cost
The first year is not the price
Cheap first-year offers are how the industry sells extensions nobody would pick at full price. Onomatix ranks registrars by total cost over five years, so the promotional year stops hiding the four that follow.
| Extension | First year | Each year after | Five years |
|---|---|---|---|
| .cafe | $3.97 | $35.77 | $147 |
| .shop | $1.77 | $26.93 | $109 |
| .io | $24.11 | $44.42 | $202 |
| .com | $9.50 | $9.50 | $48 |
The cheapest first year is regularly the most expensive domain you
can buy. A .shop at $1.77 costs more than twice a .com by year five.
How it works
Brief in, verified names out
Describe the business
One plain sentence. A language model writes brandable names from it — invented words, blends and roots, never dictionary terms that were registered in 1998.
Ask the registries
Each name is checked the moment it is written, across the extensions that fit your sector and market. The first free domain lands in about a second.
Compare what it costs
Prices from 1,321 extensions are compared across registrars, ranked by five-year total, and each name links to whichever one is genuinely cheapest.
FAQ
Questions worth asking
How is this different from other domain name generators?
Most generators guess availability from a cached list or a DNS lookup. Onomatix queries the registry itself over RDAP: a 404 means no registration exists, a 200 means the domain is taken. Where an extension has no RDAP server, it falls back to WHOIS on port 43, and only then to DNS delegation — which is shown as non-authoritative.
Does “available” mean I can definitely register the name?
It means no registration exists at the registry. A name can still be reserved, priced as premium, or blocked by trademark protection. Prices shown are standard per-extension rates, so a premium name will cost more than displayed.
Why show a five-year cost instead of the price?
Because the first-year price is usually a promotion. A .cafe domain costs about $4 for the first year and roughly $42 every year after. Over five years the cheapest first-year offer is frequently the most expensive overall.
Is Onomatix free?
Yes — no account, no payment. Registration links point to the registrar with the lowest five-year cost, and some of those links are affiliate links.
Which extensions are supported?
Availability is checked for any extension with a registry endpoint — more than 1,200 top-level domains. Pricing is compared across 1,321 extensions using published rates.
