The Extension
Why .io?
It started life as the country code for the British Indian Ocean Territory. Developers then seized on the accident buried in those two letters, I/O, input/output, and .io turned into the house style for startups, dev tools and APIs. Search engines file it as a generic extension, which means it ranks worldwide the way any .com does.
Renewing a .io costs more than renewing a classic extension, and that holds true right across the market. So we put the renewal price beside the registration price before you commit to anything. WHOIS privacy is bundled at no charge. Your domain appears in the control panel moments after you register it.
Good Fit
.io works best for
- Startups and SaaS products
- Developer tools, APIs and documentation
- Tech communities and hackathon projects
- Short brandable names that .com pricing pushed out of reach
What You Get
Included with every domain
Startup-native branding
Technical readers see .io and clock it as one of theirs, which is a signal .com cannot send.
Globally generic
To a search engine .io counts as generic rather than regional, which leaves your audience free to sit anywhere on earth.
Renewal honesty
Every year, a .io costs more than the classics, wherever you buy it. We put that on screen ahead of payment rather than afterwards.
Common Questions
Questions about .io
Why does registering a .io cost more than a .com?
Wholesale fees from the registry behind .io sit above what the big generic registries charge, and every registrar prices on top of that floor. Markup is where they differ, along with how honest they are about it. Our renewal price goes up front, so the number you budget against is the real one.
Is .io safe to build a business on?
Thousands of funded startups and developer platforms already run on it, so the extension is well established. Policy for any country code rests with its registry in the end, though. If total permanence matters more to you than anything else, buy the .com alongside and keep both. That is common practice, and cheap insurance.
Does .io affect where my site can rank?
No. Classified as generic by search engines, .io picks up no geographic penalty and no regional bias. What decides your rankings is content and performance, and it makes no difference if the visitor sits in London, Lahore or Los Angeles.
