How to check one name across several endings
Type the name without an ending, tick the endings you care about, and run it. Up to twelve at a time. Each row is a separate question to a different registry, which is why they settle at slightly different speeds.
This is the tool for the moment you have picked a name and want to know what you can actually get. It is not a name generator and it does not suggest alternatives.
What do the four results mean?
| No registration found | The registry has no record. Usually registerable, but read the premium pricing note below before you plan around it. |
|---|---|
| Taken | Somebody holds it. The registrar and expiry date are shown where published. |
| Cannot check | That ending publishes no registration service, so no tool can answer. Not a statement about the name. |
| Check failed | The registry rate limited us, refused, or did not answer. Also not a statement about the name. |
Those last two are the ones to watch. A checker that renders a failed lookup as a green tick is actively harmful, because you make decisions on it. Here they stay clearly marked as unanswered.
Why is a free name sometimes not for sale?
Because the registration record says nothing about price or eligibility. Registries reserve names, block whole categories, and price a great many ordinary strings as premium, which on newer endings can mean hundreds or thousands a year rather than the usual fee.
This matters more here than on a single check. Seeing a name free across eight endings looks like an open goal, and some of those are very likely priced well above standard. Check the price at a registrar before building anything around the result.
Which endings should you check?
Depends what you are doing, and it is worth being honest that the default selection here leans toward generic endings. That is not a preference, it is availability: many country endings publish no registration service, so no tool can check them.
- A business or product.
.comstill carries the most recognition, with.coand your country ending as the usual fallbacks. - Software or a developer tool.
.dev,.appand.ioare conventional and understood. - Protecting a brand. Register the obvious variants rather than every ending in existence. Full defensive registration across the root is not achievable and not worth attempting.
Endings that cannot be checked are still selectable, and they say so plainly rather than being hidden from the list.
Why is the check limited to twelve endings?
Each ending is a separate request to a different registry, and registries limit how often any one source may ask. Every visitor here shares one outbound address, so one person checking fifty endings on repeat can get everybody throttled across every domain tool at once.
Hence the cap, plus a per-visitor limit and a shared budget per registry. If you hit a limit, the page says so rather than returning an empty result that looks like an answer.

For one name with the full reasoning behind the answer, use the domain availability checker. To see who holds a name that came back taken, use the domain registration lookup. To see every ending that exists and which ones can be checked, see the TLD directory.
