.io domains

.io reads as "input/output," the term programmers use for data flowing in and out of a system, which is why it became a default choice for developer tools, APIs, and tech startups. Technically it is the country-code TLD for the British Indian Ocean Territory, but almost nobody registers it for geographic reasons. It has been repurposed worldwide as a short, technical-sounding brand extension, and it carries clear signals of software, infrastructure, and engineering culture. It fits SaaS products, open-source projects, dev tools, and game studios well, and short names are often still available where the .com is long gone. The trade-offs versus .com are worth weighing: .io is less familiar to mainstream consumers, registration cost varies by registrar and tends to run higher than common TLDs, and as a ccTLD its long-term policy depends on the registry operator. If your audience is engineers and founders, it usually lands. If it is a broad non-technical market, .com may communicate more clearly. Check the exact name you want, since availability differs domain by domain.
