SITE.su is an online marketplace for premium domain names, offering a catalog of more than 40,000 domains, according to the site. Its listings include names in the .ru, .su, and .рф zones, with options to buy or rent selected domains. The service is designed to let customers browse available names, search by keyword or other parameters, and review listing details such as purchase and monthly rental prices. Visitors can view or download the full catalog, which the site says can include domain statistics, and contact the team through its help section or online chat.

Purchases are completed online, with the domain transferred to the buyer, while rental is arranged by assigning the customer’s DNS servers. Some rental offers include a guaranteed right to buy the domain. The marketplace also invites customers to ask questions or submit a price offer for an individual listing. SITE.su presents its service for businesses and personal projects seeking a domain name, with examples from its catalog spanning different words, topics, and supported domain endings.
