Register your .si domain name
(Slovenia)
The .si extension is the official domain of Slovenia. Yet since September 2026, the .si domain name has enjoyed success far beyond Slovenia's borders. The US federal government has officially replaced the term 'Artificial Intelligence' (AI) with 'Super Intelligence' (SI). The .si extension is fast becoming the obvious choice for start-ups and entrepreneurs working in artificial intelligence.
.si also remains the go-to extension for reaching Slovenian internet users, who place their trust in websites using their national extension.
Open to everyone, .si domain names are allocated on a 'first come, first served' basis. Whether you are launching a Super Intelligence project, protecting a brand or running a Slovenian business, register your .si domain name today!
