SITE.su is an online marketplace specializing in premium domain names, with a catalogue of more than 40,000 domains across the .ru, .su, and .рф zones. The service lets customers browse, search, and compare domain names, including keyword-focused options, and provides tools to view or download the full catalogue and search using specific criteria.

Customers can purchase a domain online, with the marketplace describing the process as an immediate transfer of administration rights, or rent a domain for a monthly fee. Rental agreements include a priority right to buy the domain during the rental period, with the purchase price fixed in the agreement; rental provides permission to change the domain’s name servers. The maximum rental agreement term is 50 months.

Listings may include purchase and rental prices, domain age, and a rating based on search and keyword data. SITE.su also offers contact options for questions or price proposals, along with guidance and online chat through its help section. The site presents sobirateli.ru as one of its available domains.
