The ending of your address is a branding choice, not a technical one. Pick the one that fits, then check your name in seconds.
We’ve written a full page on each of these 6 - .com, .ai, .io, .co, .net, and .org - because they’re the ones the decision usually comes down to. The ending you choose is about recognition and fit, not speed or SEO: search engines treat them equally. Pick the one that matches what you’re building, then check your exact name live before you commit.
The extension - also called the TLD (top-level domain) or simply the ending - is the last part of a web address: the .com in example.com. It’s part of your name, so it’s worth a moment’s thought: the right ending makes your name easy to trust and easy to type. Each card above opens the full plain-English page for that ending - who it suits, when it doesn’t, and a live search.
If you’re torn, start with what people will type. For most businesses that’s still .com. If it’s taken, or you’re building something clearly technical or AI-focused, a fitting alternative on this list often beats a compromised .com. For the full method, read how to choose a domain name. To see what each ending costs, see pricing - every price is pulled live from the registry.
Every ending has its own page: what it’s for, who it suits, the honest tradeoffs, and the live price for one registration term straight from our registrar - no markup added.
Being listed is not the same as being on sale. 39 of these ask for registrant details we don’t collect yet, so we list them with their live price and don’t sell them. The other 512 are open at checkout. Each page says plainly where its ending stands and why.
Endings that say, before anyone reads a word, that there is something here to buy.
Endings that read as technical - clear to the people who build, opaque to everyone else.
Endings that name a craft - useful when the craft is the point.
Endings that name a job or a field - precise, and sometimes credential-gated.
Endings that describe the shape of the organisation rather than what it does.
Endings that name what people do for pleasure - warm, specific, easy to say.
Endings for care, treatment, and wellbeing - the category held to the highest bar.
Endings for homes, land, and the trades that build them.
Endings that name a financial activity - and that carry more trust weight than most.
Endings for groups, causes, and personal life rather than commerce.
Endings named after a city, region, or continent - local by design.
Two-letter endings assigned to a country or territory. Some are used as words - all of them belong to a national registry with its own rules.
Endings with no built-in meaning - what they offer is a short, available name.
Included with every domain - never an add-on. More on WHOIS privacy.
