The Rise of .IO in Tech
Originally the country code for British Indian Ocean Territory, .io has been adopted by the tech industry as its own. "I/O" means input/output in computing, making it a natural fit for tech companies.
The adoption started with developers and startups who couldn't afford premium .com domains. But it's grown into something more - .io now signals tech credibility in a way that other alternative extensions don't.
Major tech companies use .io: Notion (notion.so and notion.io), Linear (linear.app, formerly linear.io), countless developer tools and APIs. The extension has achieved a level of legitimacy that .xyz, .tech, and others haven't.
For tech startups specifically, .io can actually be preferable to a weak .com. A short, memorable .io often outperforms a longer or hyphenated .com in terms of brand perception.
The premium .io domains on this page represent the best available names on this extension - names that combine the tech credibility of .io with exceptional brandability.
Developer Cred
.IO is recognized by developers as a legitimate tech extension. API products and dev tools naturally fit here.
Shorter Names Available
Quality short names are still findable on .io when .com equivalents are taken or cost millions.
Startup Standard
Many successful startups launched on .io. It's an accepted norm in the startup ecosystem.
Better Value
Premium .io domains typically cost less than equivalent .com names while still being highly respected.
When .IO is the Right Choice
Perfect for: Developer tools, APIs, SaaS products, tech startups, open source projects, and anything targeting technical audiences. If your users are developers or tech-savvy professionals, .io is a natural fit.
Works for: General B2B software, startups in any industry that wants to signal modernity, and consumer tech products with a technical angle. Many successful consumer products have launched on .io.
Less ideal for: Traditional businesses, local services, or products targeting non-technical older demographics. A law firm or accounting practice might confuse clients with a .io domain.
Consider carefully: Enterprise sales to very traditional industries. While tech-forward enterprises accept .io, some older IT departments still have a bias toward .com. Know your buyer.
The rule of thumb: if you're building something technical people will use or buy, .io is respected. If you're targeting audiences who might not know what I/O means in computing, consider whether .io adds confusion.
