about .io
Why choose a .io domain?
The favourite of startups, SaaS and developer tools. It's a strong choice when you want a name that fits your project and is available at a fair price. Register it with crypto in minutes, point it at any host, and manage your DNS yourself — or add Managed DNS for anycast speed.
Adopted by startups and developer tools because 'I/O' evokes input/output, .io has become shorthand for modern tech. Expect premium renewal pricing, but for a SaaS product, API or developer-facing brand it signals exactly the right thing.
Pair your .io with web hosting, an SSL certificate and SMTP for email — all payable in crypto.
