The Extension
Why .io?
.io started life as a small territory's country code and became something else entirely: the default address of startups, SaaS products and developer tools, read universally as input/output. If your buyers are technical, .io signals that you are too — and thousands of product names that were taken in .com are still free here.
.io renewals run dearer than the classic extensions at most registrars, which is exactly why our tag shows the renewal beside the registration before you pay. No teaser arithmetic — the price you budget is the price you keep paying.
Good Fit
.io works best for
- Startups and SaaS products with technical buyers
- Developer tools, APIs and documentation sites
- Short product names long since taken in .com
- Agencies registering client names for tech builds
On the Shelf
Included with every domain
Startup shorthand
Technical audiences read .io as one of their own — a signal .com cannot send.
Names still available
A young extension means short, clean names that vanished from .com years ago.
No renewal surprise
The year-two price is on the tag up front — which matters more on .io than most.
Common Questions
Questions about .io
Can anyone register a .io domain?
Yes — although it began as a country code, .io is open to registrants worldwide with no residency requirement, and the overwhelming majority of .io sites have no connection to the territory.
Is .io safe for a long-term business?
It is one of the most established of the tech-adopted extensions, used by thousands of funded companies. As with any country-code extension its policy rests with its registry, but it has been stable and mainstream for well over a decade.
Why do .io domains cost more than .com?
The registry's wholesale rate is simply higher. We keep our margin lean and print the renewal beside the registration, so the full picture is on the tag before any money moves.
