SITE.su is an online marketplace specializing in premium domain names, with more than 40,000 domains offered across the .ru, .su, and .рф zones. The store serves individuals and businesses looking for memorable, keyword-focused web addresses, including names suited to particular industries and themes. Customers can browse available domains, search by keywords or other parameters, and view a full catalog or download domain listings in Excel format.

SITE.su offers both domain purchases and rentals. Online purchases are designed for immediate transfer, while rental arrangements work by assigning the customer’s DNS servers. The marketplace also provides rentals with a guaranteed right to buy, giving customers an option to acquire a domain later. For listed domains, shoppers can see purchase and monthly rental prices, and some listings include details such as domain age and search-related statistics. Customers who want to negotiate or ask about a particular name can contact the store through its help section, online chat, or inquiry form. Registration and account access are available through the website.
