SITE.su is an online marketplace specializing in premium domain names for businesses and personal projects. Its catalogue features tens of thousands of domains, including keyword-based names in the .ru, .su, and .рф zones. Customers can browse available listings, search by words or other parameters, view a complete catalogue, or download domain lists for review.

The marketplace offers two ways to obtain a domain: immediate online purchase, with the domain transferred to the buyer, or rental, arranged by assigning the customer’s DNS servers. Some rental arrangements include a guaranteed right to buy the domain later. Listings display purchase and monthly rental prices, along with available age and rating information. For customers who want to negotiate or suggest a different price, the site provides a contact form and directs visitors to its help section for contact details and online chat. Registration and sign-in are also available. SITE.su presents domain selection and acquisition as a straightforward process, supporting both direct checkout and enquiries about individual names.
