What applies before and after you register. We confirm anything special before you pay.
.io
Anyone, with no local presence needed.
The territory’s status is changing after the 2024 UK–Mauritius agreement on the Chagos Islands; .io registrations continue to work normally today, but some owners keep a second extension as a fallback.
No HTTPS requirement from the registry, but every site should still use SSL.
.dev
Anyone.
On browsers’ HSTS preload list: a .dev site only loads over HTTPS, so it needs an SSL certificate from day one.
.dev is HTTPS-only: browsers refuse plain http:// for every name in the extension. Every GlobalHostia hosting plan includes free SSL, or add a certificate.
SEO: does the extension matter?
Short answer: not for rankings. Content, links and site speed decide where you rank; the extension mostly affects trust, memorability and which country search engines assume you serve.
.io
A country code that Google treats as generic, like .com: it is not tied to one country in search results and gives no ranking boost on its own.
.dev
A generic extension: no ranking advantage or penalty on its own. Search engines rank the content and the links, and let you target any country.
Myth check: no extension gets a hidden ranking bonus, and keyword extensions (like .shop or .tech) do not rank better for that keyword. Switching an established site to a new extension costs time while search engines re-learn it, so choose well up front.
Our verdict, by kind of site
Based on what each extension signals to visitors and its three-year cost at today’s prices.
Startup or SaaS product.io.io reads as a product brand to investors and users worldwide; .dev is a weaker match for a startup name.
Local businessEitherNeither is a natural fit; a broader extension such as .com usually reads better for this.
Tech or developer project.devBoth fit equally well; .dev costs less over three years at today’s prices.
Online shop.io.io tells shoppers they can buy here or is the address they trust most; .dev fits a shop less naturally.
Non-profit or community.dev.dev is the better fit for an organisation or community; .io reads as more commercial or technical.
Personal brand or portfolio.dev.dev reads naturally as a personal name or portfolio; .io is less personal.

If the name is your brand, yes: register your main extension and point the other to it. It stops look-alike sites and catches visitors who type the other one. Both together cost A$73.42 for the first year.
