Get a .io — the de facto ending for tech.

Originally the country code for the British Indian Ocean Territory, .io became the unofficial home of developer tools, SaaS, and modern tech startups. If you build for technical users, .io signals you're one of them.

Who picks .io?

  • Developer tools and APIs
  • B2B SaaS for technical buyers
  • Early-stage tech startups

What it signals

Modern, technical, "we know what we're doing." Used by GitHub, Sentry, Linear, and a thousand other tools your developers already trust.

Pros

  • Strong "we're a tech company" signal.
  • Way more short, memorable names still available than .com.
  • Tech crowd reads .io as a credible alternative to .com.
  • Common pattern in product naming (e.g., something.io).

Watch-outs

  • Premium price (~$50/yr) — much more than .com.
  • Less recognized by non-tech consumers.
  • Country-code TLDs have historically had outage risk (rare, but worth noting).
