SITE.su is an online marketplace specializing in premium domain names for businesses and digital projects. Its catalogue features tens of thousands of domains, including keyword-based names and website addresses in the .ru, .su, and .рф extensions. Customers can browse available listings, search by words or other criteria, view related name suggestions, and download a complete catalogue in Excel format.

The marketplace offers two ways to secure a domain: immediate online purchase, with the domain transferred upon purchase, or rental, arranged by assigning the customer’s DNS servers. Rental options may include a guaranteed right to buy the domain later. Listings display prices for both purchase and rental, and some also provide information such as domain age and search-related indicators.

Visitors can contact the marketplace to ask questions about a specific domain or propose a price. SITE.su also provides help, registration and login facilities, and access to contact details and an online chat. Its services are designed to help customers find and obtain domain names for their internet projects.
