All premium names

Choosing one

A short name earns its keep when people can spell it after hearing it once. Read each one aloud: if you have to spell it out, keep looking.

Six letters is a sweet spot. Short enough for a logo, an app icon and a terminal command, long enough to still be a word people can say.

How these names are checked

A name is listed only after the official .si records show that no one holds it. Listed names are checked again in rotation, and a name someone registers drops out at the next update. The .com, .ai and .io marks come from a quick look, not a confirmed answer.

How names are checked

How to register one

Free .si names are registered at any .si registrar, such as Dynadot or Name.com, not bought from Hivex. .si is open to everyone worldwide. Availability changes all the time, so confirm at the registrar before you pay.
