The Extension
Why .io?
.io began as the country code for the British Indian Ocean Territory, but developers adopted it for its accidental meaning — I/O, input/output — and it became the house style of startups, dev tools and APIs. Search engines treat it as a generic extension, so it ranks globally like any .com.
.io renewals run higher than the classic extensions across the whole market, which is exactly why we show the renewal price beside the register price before you commit. WHOIS privacy is included free, and the domain is live in your control panel within moments of registering.
Good Fit
.io works best for
- Startups and SaaS products
- Developer tools, APIs and documentation
- Tech communities and hackathon projects
- Short, brandable names the .com market priced out
What You Get
Included with every domain
Startup-native branding
To technical audiences .io reads as one of their own — a signal .com can't send.
Globally generic
Search engines rank .io as a generic extension, not a regional one, so your audience can be anywhere.
Renewal honesty
.io costs more per year than the classics everywhere — we simply say so on screen before you pay, not after.
Common Questions
Questions about .io
Why are .io domains more expensive than .com?
The registry behind .io sets higher wholesale fees than the big generic registries, and every registrar builds on that base. What varies between registrars is markup and honesty — we show our renewal price up front so you can budget on the real number.
Is .io safe to build a business on?
It's an established extension used by thousands of funded startups and developer platforms. Like any country-code extension its policy ultimately sits with its registry, so if absolute permanence is your top priority, register the .com too and hold both — a common and cheap insurance.
Does .io affect where my site can rank?
No — search engines classify .io as generic, so it carries no geographic penalty or bias. Your content and performance decide your rankings, whether visitors are in London, Lahore or Los Angeles.
