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 individuals and businesses find keyword-focused domains for websites and online projects, with listings that can be searched by name, topic, or other parameters. Visitors can view or download the full domain catalogue, including information such as age and search-related ratings, and contact the marketplace team through its help section or online chat.

Domains are available for immediate purchase or rental. Purchasing is completed online with the transfer of domain administration rights. Rental is arranged by assigning the customer’s DNS servers and includes a contractual priority right to buy the domain during the rental period, with the purchase price fixed in the agreement. Rental prices are shown per calendar month, and agreements can run for up to 50 months. Customers can also enquire about a specific domain or propose a price.
