SITE.su is an online marketplace for premium domain names, offering more than 39,000 listings across the .ru, .su, and .рф domains. The service enables customers to buy a domain outright or rent it, with rental options that include a guaranteed right to purchase. Purchases and rentals can be completed online; purchased domains are transferred immediately, while rentals are set up by assigning the customer’s DNS servers.

The marketplace provides tools to browse and compare available names, including an expanded search, listings of matching or related domains, and downloadable catalogues in Excel format. Listings display prices for both purchase and rental, and may include information such as domain age, ratings, and search statistics. Customers can add a domain to their cart for an immediate transaction or contact the seller to ask questions and propose a price. Support and online chat are available through the Help section. SITE.su serves individuals and businesses seeking a domain for an online project, with options to suit different budgets and ownership preferences.
