Is .io Dying? What to Buy Instead

Understanding buy instead is the foundation of this guide. Below we break it down step by step so you can act with confidence.

In 2024, the UK agreed to transfer sovereignty of the Chagos Islands to Mauritius. That matters to you because .io is the country-code TLD for the British Indian Ocean Territory — and when a country ceases to exist as a distinct entity, its ccTLD can be retired.

It hasn't happened yet. ICANN hasn't made a ruling. But the precedent exists (.su for the Soviet Union lingered, .yu for Yugoslavia was eventually deleted), and the uncertainty alone is enough to change how smart founders and investors approach .io.

Buy Instead: What actually happened

The UK announced in October 2024 that it would cede sovereignty of the Chagos Islands to Mauritius after decades of dispute. The treaty hasn't been ratified yet, and the timeline remains uncertain. But the announcement triggered a wave of concern in the tech community because the .io extension, managed under British authority, could theoretically be retired or transferred under ICANN rules if the underlying territory code (IO) is removed from the ISO 3166-1 standard.

How worried should you be?

Moderately. There's no immediate risk — existing .io domains continue to resolve normally, and any ICANN transition would take years and likely include a lengthy sunset period. But the perception of risk is already real: some companies have begun migrating away from .io, and investors are discounting .io names in portfolio valuations. Perception drives behaviour, even before policy does.

The best alternatives to .io

.com remains the safest long-term bet — no sovereignty risk, maximum trust. .ai has absorbed much of .io's developer-community cachet and has no comparable geopolitical risk (Anguilla's sovereignty is not in question). .dev and .app are Google-operated gTLDs with no country-code risk. .si is emerging for the superintelligence niche. For a tech startup in 2026, .ai is the natural successor to .io's cultural role.

What to do with your existing .io domain

Don't panic-migrate. If you have a strong brand on .io, keep it running while you acquire the .com and/or .ai equivalent. Set up the new domain, build authority on it, then 301-redirect the .io when you're ready. The transition is a normal domain migration — Search Console change-of-address, 301 every URL, monitor coverage. The important thing is to start the acquisition now, not to rush the migration.

When evaluating buy instead, start with the fundamentals: what problem it solves, who it serves, and how it compares to the alternatives buyers consider first.

Start with the fundamentals. Define who you are serving, the single outcome you want, and the budget you are comfortable committing before you compare any options.

A practical rule is to favour clarity over cleverness. The choice that is easiest to understand, spell, remember and act on tends to win over the long run.

Context changes the answer. What is optimal for a fast-moving startup is rarely optimal for an established brand, so weigh your own stage, market and ambitions.

Avoid the common mistakes: rushing the decision, copying competitors blindly, and ignoring the total cost of ownership beyond the very first year of use.

Think in terms of trade-offs rather than a single perfect answer. Every option trades memorability, cost, reach and flexibility in a slightly different mix.

Document your reasoning. Writing down why you chose one path makes it far easier to revisit the decision later and to explain it to partners and investors.

Test with real people. A quick check with a handful of your actual customers will surface problems that no amount of internal debate ever reveals.

Plan for growth. The option that fits today should still make sense when your audience, catalogue or team is several times larger than it is right now.

Finally, revisit the decision periodically. Markets, tools and best practices move quickly, and a choice that was ideal last year may deserve a fresh look today.

Frequently asked questions

Will my .io domain stop working?

Not any time soon. Even if the Chagos sovereignty transfer is completed and ICANN retires the .io code, there would be a multi-year sunset period. But the uncertainty is real, and acquiring an alternative now is smart.

Should I buy a .ai domain instead of .io?

For a tech startup, yes — .ai has inherited .io's cultural signal and doesn't carry the geopolitical risk.

Is .io still safe for a new project?

It works today, but launching a new brand on an extension with existential uncertainty is a harder sell. .com or .ai is the safer choice for something new.
