SITE.su is an online marketplace specializing in premium domain names, with more than 40,000 domains available across the .ru, .su, and .рф zones. The service enables customers to purchase a domain immediately or rent it by the month, with rental agreements offering a priority right to buy and a purchase price fixed in the contract. Customers can search by keywords or other parameters, view matching domains, browse or download the full inventory, and contact the marketplace to ask questions or propose a price.

Purchasing transfers the domain’s administration rights, while renting allows the customer to assign their own name servers. Rental terms can last up to 50 months. Listings include information such as price, domain age, and indicators based on search and keyword data. The marketplace also provides registration and sign-in, a help section with contacts and online chat, and an inquiry form requiring an email address and telephone number. SITE.su presents domain acquisition and rental as flexible options for businesses and other online projects seeking a suitable web address.
