This tool estimates availability by asking Cloudflare's DNS resolver for each name's SOA record. If the resolver returns NXDOMAIN, meaning no such domain exists in the global DNS, the name is marked Available. The catch is that a domain can be registered yet have no active DNS zone — someone may own it for parking, resale, or a future launch without ever publishing records. In that case the DNS lookup sees nothing and reports it as free even though you cannot buy it. Premium, reserved, and recently expired names can behave the same way. That is why DNS checking is a fast shortlisting estimate, not a purchase guarantee. Use the tool to narrow hundreds of ideas down to a handful of promising candidates, then always confirm the exact name at a registrar before you commit money to it.

From a single keyword the tool builds 25 base names: your bare keyword plus 24 short startup-style suffix blends such as hub, hq, pro, labs, ai, ly, cloud, get, try, go, now, space, and smart. Each of those names is then paired with every TLD you have selected, so the total candidate count is 25 multiplied by the number of extensions you toggle on. With the three default extensions (.com, .net, .io) that is 75 domains in one run, and selecting all seven supported TLDs produces 175 candidates checked back to back. This mirrors how real product names form — a recognizable root plus a modern modifier — so even when the plain .com is long gone, a blend is often still open. Enter a keyword, pick your extensions, and generate a full batch in seconds.

Each candidate gets one of three labels: Available, Taken, or Unknown. Available means the DNS query returned NXDOMAIN, so no record exists and the name is likely free. Taken means an SOA record was found, so the domain already has an active DNS zone. Unknown appears when the lookup itself fails — for example a network hiccup, a timeout, or an unexpected resolver response — so the tool genuinely cannot tell either way rather than guessing. An Unknown result is not the same as Taken; it simply means that particular check did not complete. If you see several Unknowns, re-running the keyword usually resolves them, since the queries are sent one by one. Treat Unknown names as worth a manual look at a registrar if you like them. Generate again to retry any that did not return a clean answer.

It depends on your audience, but a few conventions hold up well. The .com extension is still the most trusted and the easiest for people to type from memory, so claim it whenever it is available. When the .com is gone, .io and .co are the popular fallbacks for tech and SaaS brands because they read as modern and are widely recognized. The .app and .dev extensions are run by Google and served over HTTPS only, which suits product and developer projects, while .org traditionally signals nonprofits, communities, and open-source work. This tool lets you check all seven — .com, .net, .org, .io, .co, .app, and .dev — and toggle any combination before generating. Turn on the extensions that fit your project, run your keyword, and compare which blends are open across each one side by side.

Before generating ideas, the tool sanitizes your keyword locally and keeps only letters and digits, lowercasing everything in the process. So an entry like "My Cafe!" becomes "mycafe" and "go-fast 2" becomes "gofast2". This happens because the registrable part of a domain name cannot contain spaces, punctuation, or most symbols — only letters, numbers, and hyphens are valid, and the tool builds clean single-word roots to blend with its suffixes. Stripping these characters up front means every candidate it produces is a name you could actually register, rather than something a registrar would reject. It also keeps suggestions short and brandable, which matters for memorability. If you want a hyphenated or multi-word idea, generate from the core word first, then adapt the favorites you copy. Type any phrase and the tool turns it into usable roots automatically.
