SITE.su is an online marketplace specializing in premium domain names, offering more than 40,000 domains in the .ru, .su, and .рф zones. The service is designed for businesses and individuals seeking a domain for a website, brand, or personal project. Customers can browse available names, search by keywords or other parameters, view a full domain catalogue, and download listings with selected metrics.

Domains can be purchased online, with the transfer of administration rights described as immediate, or rented by the month. Rental involves assigning the customer’s DNS servers and includes a contractual priority right to buy the domain during the rental period, at a price fixed in the agreement. Contracts can last up to 50 months. The marketplace displays purchase and rental prices alongside information such as domain age and search-related indicators. Customers can contact the store with questions or propose a price through its inquiry form, and assistance and online chat are available in the Help section.
