.com vs .io: is .io still worth it in 2026?

Updated May 11, 2026

.io has been the developer-and-startup TLD for fifteen years. In 2026 the calculus is changing — fast. Here's when to still pick .io, when to skip it, and a fresh note on the British Indian Ocean Territory situation that you should be aware of before you spend money.

The 2024-2025 .io geopolitical wrinkle

In 2024 the UK announced it would cede sovereignty over the British Indian Ocean Territory to Mauritius. The .io ccTLD is administratively tied to that territory. The IANA has not yet announced .io's fate, and registrations remain renewable, but several large companies (including GitHub) have publicly moved to other TLDs as a precaution.

Heads upPlain English: .io is unlikely to disappear overnight, but it is no longer the safe long-term choice it was in 2018. If your product needs to outlive the next decade on the same URL, factor that in.

Developer perception

.io still reads as "serious software" to technical buyers — it has trailed a generation of well-known dev tools (Twilio.io, Lottie.io, lots of open-source projects). On a CV-quality engineering brand, .io still works. But on a less technical audience — finance, ecommerce, B2C — .io can read as cryptic.

Cost reality

	.com	.io
Annual price	~$10-15	~$40-60
Premium prices	$$$$	$$$
Geographic restrictions	None	None (despite being a ccTLD)
DNSSEC	Yes	Yes

When .io still wins

Your product is developer-facing (CLI, library, SDK, API service).
Your audience's muscle memory already expects technical brands on .io.
The matching .com is gone and the matching .ai doesn't fit your positioning.
You want a four- or five-letter name that's available on .io but not .com.

When to skip .io

B2C consumers or any non-technical buyer set.
You're building for a 10+ year horizon and the BIOT/Mauritius situation worries you.
.dev is available and your product is developer-focused — .dev is now arguably the cleaner choice for dev tools (always-HTTPS, more semantic).
You want offline marketing to work easily — "dot eye-oh" still confuses non-technical listeners.

What about .co?

.co is Colombia's ccTLD, marketed as a .com alternative. It has the advantage of being pronounceable and not technically off-brand for any industry. It's a reasonable second choice when .com is taken. It does not have .io's developer cachet.

Frequently asked

Will .io domains stop working when sovereignty changes?+

Almost certainly no — the precedent for ccTLD migrations is long, slow, and grandfather-existing-registrations. But it's no longer the maintenance-free decade-long bet it was. Diversify if it matters.

Should I move my .io to .com?+

If a clean matching .com is available at a fair price, and you're below 10K monthly visitors, the migration cost is low. Above that, the SEO and email reconfiguration costs grow fast — it becomes a real project.

What about .io vs .ai for a dev tool?+

.io for developer tools that aren't themselves AI products. .ai for tools that wrap or expose an LLM. Both work for AI infra.
