Check one name across hundreds of domain extensions at once: which are free, what they cost and where to register them.
Some registrar links are paid links (marked “paid link”): TLDscout earns a commission if you buy through them. It doesn't change your price or the order of results. How TLDscout makes money and ranks results
Availability isn't guaranteed until you register: registries may reserve names or charge premium prices. Prices are Porkbun's and Cloudflare's published standard prices in USD, as of the time shown, before VAT or sales tax; the registrar's checkout is final. TLDscout isn't a registrar and isn't affiliated with or endorsed by any registrar or registry.
Each name first gets a free DNS check: if the extension's own nameservers delegate it, it's Taken (in DNS). Names with no delegation then go to the registry: its RDAP server, WHOIS for extensions without RDAP, or Google Registry's own check for Google's extensions (.app, .dev and others). Definite answers (Taken, Available, Reserved) are saved, so a repeat search asks the registries again only about names they didn't confirm, and not while a registry's lookup limit is in force. Registries limit how often they can be asked; TLDscout keeps to their limits and says so when one is in force.
Prices are the registrars' standard prices per year, from their price lists. An extension with a minimum term (such as .ai, 2 years) also shows the minimum checkout (the first year plus renewals up to the minimum), and Cheapest first sorts by that. A steep renewal shows on the button ("then $50.98/yr"). Registries can charge more for some names (premium names). Google Registry says so: those rows read "Premium at the registry (price not shown)", or "price not confirmed (premium check unavailable)" when its check couldn't answer. Most other registries don't say, so an Available row there notes “Standard price; the registry may charge more for this name” (not on .com and .net, which have no premium names).
Every name gets a DNS check only: TLDscout asks the extension's own nameservers whether the name is delegated. It doesn't ask any registry by itself. Verify with the registry asks the registry about that one name, and only where the registry's terms allow lookups made to help someone register a name. Where they don't, the row says Check at a registrar and links to registrars instead; for a few extensions (such as .gg and .je) there's no lookup at all. Verify shows the registry's answer (registered or not), never its record. What TLDscout asks registries.
Porkbun's and Cloudflare's prices are their published standard prices per year, shown as reference prices: TLDscout earns nothing from them. Each says when its price list was fetched. An extension with a minimum term (such as .ai, 2 years) also shows the minimum checkout. Registries can charge more for some names (premium names), which a price list doesn't show, so an open row notes “Standard price; the registry may charge more for this name” (not on .com and .net, which have no premium names). The other registrar buttons show no price. Some of them may be paid links; each says so. How TLDscout makes money and ranks results.
Check price at Porkbun asks Porkbun about that one name: its price for it (premium or standard, first year and renewal), labelled with the time it was checked ("saved answer" when TLDscout reused Porkbun's reply from the last few hours). If Porkbun can't register a name, that may mean it's registered, reserved or simply not offered there; TLDscout never counts that as Taken. If Porkbun can register a name nobody confirmed, the row becomes Available, "confirmed by Porkbun". Only Porkbun is asked: when it says premium, other registrars' buttons read "likely premium", an inference.
