Registrars often advertise a low first-year price as a hook, then charge the standard rate every year after that. The introductory deal applies once; the renewal price is what you actually pay for the life of the domain. The gap can be dramatic: a .online might register near $2.99 but renew around $34.99, and a .store can jump from a few dollars to roughly $59.99 a year, while a steady .com stays around $13–$15 annually. Over five or ten years, the renewal column matters far more than the headline. That is why this checker shows both an indicative first-year price and the renewal cost on every result card, so you compare the true long-term expense instead of just the cheapest sticker. Always read the renewal figure before you commit to an extension.

The tool grades the bare name out of 100 using four equally weighted factors worth 25 points each. Length rewards short names: five characters or fewer scores highest, and anything past twelve is penalized. Pronounceability looks at the vowel-to-consonant balance, scoring full marks when roughly a quarter to half the letters are vowels, since a name you can say aloud is easier to share. Clean characters gives full marks to names with no digits or hyphens, because those invite typos and misheard spellings. Memorability rewards a good variety of distinct letters, which makes a name easier to recall and spell. A total of 80 or above signals an excellent brand, 60–79 is solid, and below that suggests reaching for an alternative. Type a name to see its score broken down by factor.

A gTLD, or generic top-level domain, is a global extension anyone can register regardless of location — .com, .net, .org, plus newer options like .io, .ai, .app, .online, and .xyz. A country-code TLD, or ccTLD, is tied to a specific country or territory: .us for the United States, .uk for the United Kingdom, .de for Germany, and .ca for Canada. ccTLDs signal regional presence and can build local trust, though some carry residency or registration requirements depending on the registry. gTLDs are the safer default for a brand meant to reach a worldwide audience. This checker covers 16 extensions across both types, grouped into popular, tech, business, country, and new-gTLD categories, so you can weigh a global reach against a local one side by side.

Start by reconsidering the extension: if the .com is gone, a .io, .co, or .dev may still be open and perfectly credible for your audience. Next, try reshaping the name itself — this tool generates alternatives automatically by adding familiar prefixes like get, try, use, my, and go, suffixes like app, hub, labs, and hq, and simple tweaks such as pluralizing the word. Those small changes often surface an available, brandable option close to your original idea. You can copy any available suggestion with one click or re-search it instantly to begin a fresh comparison. If you still want the taken name, use the WHOIS button to see who owns it; some domains are parked or listed for sale, and the current registrant may be open to a transfer. Brainstorm a few backups before settling.

No — the green and red availability labels in the results grid are simulated for demonstration, generated deterministically from the name and extension rather than queried live from a registrar, and the tool states this directly with an on-screen notice. They exist to help you explore name ideas, compare extensions, and read brandability scores quickly without hitting any live lookup limits. Treat the grid as a brainstorming canvas, not a final answer. When a name looks promising, confirm its true status at the source: the Register button hands you off to Namecheap to check and buy, and the WHOIS button opens whois.com to reveal who already owns a taken domain. Always verify a candidate with one of those real services before spending money, then export your shortlist as a CSV to carry it to whichever registrar you trust.
