About .io

The .io extension was originally designated for British Indian Ocean Territory, but it has gained popularity among tech companies, startups, and developers due to its association with "input/output" in computing.

Today, .io is widely used by tech-forward businesses, app developers, and gaming platforms. Its modern, innovative appeal and broader availability compared to more traditional domains like .com make it a favored choice for technology-focused brands and startups.
