.io was originally the country-code domain of the British Indian Ocean Territory, but the tech community has practically made it its own – in the IT world it reads as "input/output". Today it is managed by the Identity Digital registry and is used by startups, SaaS tools, and developer and gaming projects.

Anyone can register .io, with no requirement on residence or field. It is one of the more prestigious and also pricier extensions – you can see the exact registration and renewal prices in the cards above.
