SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains in the .ru, .su, and .рф zones. The service enables customers to purchase domains or rent them by the month, with online transactions designed for immediate processing. A purchase transfers domain administration rights, while rental lets customers assign their own name servers. Rental agreements include a priority right to buy the domain during the contract period, with the purchase price fixed in advance; contracts may last up to 50 months.

Customers can browse the full domain catalogue, download a spreadsheet, or use advanced search to find names by keywords and other criteria. Listings provide details such as purchase and rental prices, domain age, and an SEO-oriented rating based on Yandex Wordstat and search-engine data. Interested buyers can contact the marketplace with a question or offer, and support is available through its help section and online chat. SITE.su presents domain acquisition and rental as flexible options for businesses and personal projects seeking a suitable online address.
