SITE.su is an online marketplace for premium domain names, offering more than 40,000 domains across the .ru, .su, and .рф zones. The service helps businesses and individuals find, buy, or rent domain names, including keyword-based options. Customers can browse the full catalog, search by terms or other parameters, download a domain list, and contact the marketplace through its help section or online chat.

Purchases are completed online, with domain administration rights transferred immediately. For customers who prefer not to buy outright, SITE.su offers monthly rentals that allow the renter to change the domain’s name server settings. Rental agreements include a priority right to purchase the domain during the agreement, with the buyout price fixed in the contract; terms can run for up to 50 months. Listings show purchase and rental prices, domain age, and rating information based on search-related indicators. Customers can also submit questions or make an offer on a specific domain.
