SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains across the .ru, .su, and .рф zones. The platform helps businesses and individuals find memorable, keyword-based addresses for websites and online projects, with search tools for exploring names by wording, translation, and transliteration. Users can browse the full inventory, download a domain list in Excel, and review available information such as age, ratings, and search statistics.

SITE.su offers two ways to obtain a domain: immediate online purchase with transfer, or rental through the assignment of the customer’s DNS servers. Rental options include a guaranteed right to buy the domain, and customers can contact the marketplace to ask questions or propose a price. The site supports online ordering and provides help and contact information, including an online chat. Its listings display purchase prices in rubles and monthly rental rates, enabling customers to compare options and select a domain suited to a business or personal project.
