Best Domain Extensions for 2027 (Ranked by Use)

The best domain extensions for 2027 at a glance

If you only remember one rule: start with the .com, then choose the extension that best describes what you do or where you are. New to extensions in general? What is a TLD? explains the basics.

The safest all-rounders

.com: still the default

Nothing beats .com for recognition. People type it by habit, it works for any kind of project in any country, and it's the one extension nobody questions. The only problem is availability: almost every short, common word has gone. If your exact name is free as a .com, take it.

.co: the short alternative

.co is a country code (Colombia) that's used worldwide as shorthand for "company". It's a strong second choice for startups and businesses, with one catch: people sometimes type .com by mistake, so it's worth owning the .com too if it ever becomes available.

.net and .org

.net suits networks, tools and online services; .org is open to anyone but still reads as a non-profit, community or open-source project. Both are trusted, but neither is the obvious choice for a new brand in 2027.

What about .info, .biz and .xyz?

All three are generic and open to anyone, and short names are easier to find in them. .info works for information sites and guides, .biz for small businesses, and .xyz is popular with tech and crypto projects. They're less familiar than .com or .co, so they suit side projects and secondary domains better than a main brand, and it's worth checking their renewal prices, which can be well above the first-year offer.

Best domain extensions for tech and AI

.ai

.ai (Anguilla's country code) has become the default signal for artificial intelligence products. If you're building in AI, a short .ai often lands better with users and investors than a long .com. It's one of the more expensive extensions to register and renew, so check the price first. The .ai domain checker shows whether your name is free.

.io

.io has been the startup and developer favourite for years. It's well understood in tech circles and less so outside them, so it suits developer tools, APIs and B2B software better than consumer brands. See the .io domain checker.

.app and .dev

Both are run by Google's registry and are on browsers' HTTPS-only list, so every site on them must use HTTPS. That's a security plus, and the meaning is instantly clear: .app for apps, .dev for developers and their projects.

.tech

A descriptive option for tech companies and products that's usually easier to find available than .io or .ai.

Best domain extensions for creators and personal brands

Creators increasingly use their own domain for a link-in-bio page, a newsletter, a shop or a portfolio, so the name usually matches the social handle.

The key is consistency: the domain should match your Instagram, TikTok and YouTube handles. The username checker checks the handle and 15 popular extensions in one search, and link in bio custom domain shows how to use your domain with a link page.

Best domain extensions for online shops and local businesses

.shop and .store

Both tell visitors straight away that they can buy something, and short names are often still available. They're frequently discounted in the first year, so compare the renewal price before you commit.

Your country code

For a business that serves one country, its country code (.uk, .ca, .de, .fr, .au and so on) builds local trust and tells search engines where you trade. Some require a local presence: .ca needs a Canadian connection, .eu an EU/EEA address and .us a US connection.

Niche and descriptive extensions

Extensions like .coffee, .fitness, .photography or .agency can make a short, descriptive name possible: novabeans.coffee rather than novabeanscoffeeshop.com. They work best when the extension really describes the business.

Domain extensions to think twice about

No extension is bad in itself, but some come with trade-offs worth knowing before you build on them.

• Ultra-cheap extensions with steep renewals: a 99¢ first year can become $30 to $60 a year afterwards. How much does a domain name cost? shows how that adds up.
• Extensions with a spammy reputation: some low-cost extensions appear often in spam reports, so email and links on them are more likely to be filtered. Check how an extension is used before you send business email from it.
• Very long or obscure extensions: if people don't recognise the ending, they may assume your address is wrong or type .com instead.
• Country codes with residency rules you can't meet, or whose rules could change.
• Premium-priced names that renew at the premium price every year.

What's changing with domain names in 2027

More creators and small businesses on their own domains

Owning your name has become the safe option as social platforms change their rules and reach. A personal domain that forwards to a link page, a shop or a newsletter keeps your audience reachable wherever you post.

Email on your own domain matters more

Major email providers now require bulk senders to authenticate their mail, which you can only fully set up on a domain you control. Even if you don't send in bulk, email from [email protected] looks more trustworthy than a free webmail address.

More extensions are on the way

ICANN, which oversees domain extensions, has been preparing its first new round of generic extensions since 2012. As new endings are approved and launched over the next few years, expect more choice, including more brand and niche extensions.

AI names keep getting scarcer

Short, meaningful .ai and AI-themed .com names are among the fastest to be taken. If you're building in AI, secure the name early.

How to choose and check your extension

1. Check the .com first. If it's free and short, it's usually the answer.
2. Shortlist two or three extensions that describe your project or audience, using the tables above.
3. Check them all at once with the TLD checker, which searches 100+ extensions in groups.
4. Compare renewal prices, not just the first-year offer.
5. Check the social handles for the same name with the username checker.
6. Register your favourite today, plus the .com if it's free and you're building a brand.

Conclusion

Recap

.com remains the best all-round extension for 2027, with .co as the closest alternative. For tech, .ai, .io, .app and .dev are the strongest picks; creators do well with .com, .me, .tv or .gg; shops suit .shop or .store; and local businesses benefit from their country code.

Think twice about ultra-cheap extensions with high renewals, endings with a spammy reputation, and premium names that renew at premium prices.

Final thoughts

The best extension is the one that gives you a short, clear name that matches your social handles and that you'll happily renew every year. Check your shortlist on the TLD checker, compare renewal prices, and register the winner before someone else does.
