Expiring .io Domains for Sale
All .io domains are just $99. No negotiation, no hidden fees.
The .io extension is technically the country code TLD for the British Indian Ocean Territory, but it has been adopted by the global tech community as the go-to extension for startups, developer tools, and technology companies.
The popularity of .io exploded in the 2010s when startups began choosing it as a hip, modern alternative to .com. The "IO" letters also resonate with developers as they stand for "input/output" — a fundamental computing concept.
Why .io domains are valuable:
- Strong tech and startup credibility
- Short and clean-looking URLs
- "Input/Output" association with developers
- Popular for SaaS and API products
- Growing recognition among mainstream users
Who should buy .io domains:
- Tech startups and SaaS companies
- Developer tools and APIs
- Gaming companies
- Blockchain and crypto projects
- Anyone wanting a modern, techy vibe
Companies like Socket.io, Itch.io, and Figma (originally at figma.io) have helped cement .io as the startup extension of choice. NotRenewing often has quality .io domains listed at just $99 — far less than what new .io registrations cost at premium pricing.
