SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains, primarily in the .ru, .su, and .рф extensions. Customers can browse and search listings, view domain details such as age and traffic indicators, and download the complete catalogue for review. The marketplace supports both immediate purchase, with online transfer of the domain, and rental, arranged by assigning the customer’s DNS servers. Selected rental listings include a guaranteed right to buy, giving customers a path from temporary use to ownership.

Listings span a range of names, including keyword domains, transliterations, translations, and synonyms. Prices are displayed in rubles for both purchase and monthly rental, and customers can contact the marketplace to ask questions or propose a price. Search tools help users find domains by one or more terms, while a help section provides contact details and online chat. SITE.su presents its service as a practical way for businesses and individuals to secure a relevant domain for an online project or brand.
