Is .io better than .com for a startup?

Which should you buy, .io or .com?

Buy the .com if it is free or affordable, and add the .io only if your users are developers. A .com needs no explanation to customers, banks or anyone who hears your email address. A .io tells engineers that the product is software. That helps a developer tool and does little for anyone else.

DotAlmanac is a domain extension guide and registrar: compare every extension, then register it with no KYC and pay in crypto. We sell both extensions, so the verdict below follows cost and fit, not what we earn on each one. Every price on this page is also on our pricing page.

How much more does a .io cost than a .com over 5 years?

A .io costs about four times as much as a .com over 5 years at DotAlmanac. The sums, as of 29 October 2026: $33.99 + 4 × $52.49 = $243.95 for .io, and $11.99 + 4 × $11.99 = $59.95 for .com.

The gap comes from the renewal. According to DotAlmanac's price grid on 29 October 2026, 35 of 43 extensions cost more to renew than to register. .io has the second-largest jump, +54 %, after .app at +67 %. .com is one of the 8 that renew at the first-year price.

The mistake is to budget the first year only; why renewals cost more explains the jump.

Is the Chagos question a real risk for a .io domain?

It is a long-term risk, not a current problem: .io works normally as of 29 October 2026. The extension stands for the British Indian Ocean Territory, the UK territory that includes the Chagos Islands. A country code depends on the territory it names, so a change of sovereignty raises questions about its future.

The treaty between the United Kingdom and Mauritius on the Chagos Islands was frozen in 2026. The registry is Internet Computer Bureau Limited, a subsidiary of Identity Digital.

Our reading: for a product you may rename within 5 years, this changes nothing. For a name you plan to keep for decades, hold the .com as well, or keep a fallback name ready.

Do people trust a .io address as much as a .com?

Developers and tech investors do; the general public treats .com as the normal ending. A customer who hears your brand name once will often type .com from habit. If someone else owns that .com, they receive your lost visitors and part of your misdirected email.

So look at the .com first. If an active company in your field owns it, choose another name; if it is parked, the .io works. Our guide on checking availability shows how.

Where can you buy .io or .com for less than at DotAlmanac?

Porkbun and Cloudflare sell both for less, and we say so. Porkbun lists a .io at $28.12 for the first year, against $33.99 here (19 October 2026). Cloudflare Registrar lists .com at $10.46 and .io renewals at $50.00 (8 October 2026). On these two extensions we are not the low-cost option.

The accounts differ more than the prices. Porkbun may ask some new accounts for a photo ID through Veriff. Cloudflare documents no crypto payment and requires its own DNS. DotAlmanac asks for no ID, takes BTC, USDT, USDC, ETH, SOL, LTC, and prints each renewal price next to the first-year price.

Can you check whether the .io and the .com are both free?

Yes: one search in our client area checks a name in several extensions. It asks the registry's RDAP service first, then a commercial WHOIS service where RDAP is not usable. For .io, the result can read Availability confirmed at order: the final check happens at registration. If the name was taken in the meantime, if a domain cannot be registered (taken in the meantime, registry refusal), the full amount goes back to your balance.
