What is a .io domain?
.io is the country-code domain of the British Indian Ocean Territory, but the tech world adopted it because “io” reads as input/output. It has become the signature extension for startups, SaaS products, developer tools and side projects.
Registration prices are higher than most extensions, and there are no location requirements. Choose .io when you want a short, modern name that instantly signals “tech”.
