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 names by keyword, transliteration, synonyms, or translation, and use advanced search to find options suited to a business or personal project. The catalogue includes listings with purchase and monthly rental prices, alongside details such as domain age and search-related ratings.

The marketplace supports both immediate purchases and rentals. Buying is completed online with instant domain transfer, while rental works by assigning the customer’s DNS servers. Some rental arrangements include a guaranteed right to buy the domain later. Visitors can view or download the full domain list, including data such as search metrics, and contact the team through the Help section or online chat. For a specific domain, customers may submit a question or propose a price. SITE.su presents domain names as available assets for developing an online presence, with listings such as limity.ru and its Cyrillic equivalent Лимиты.рф illustrating the range of options.
