SITE.su is an online marketplace specializing in premium domain names, with a catalogue of more than 40,000 domains, primarily in the .ru, .su, and .рф zones. The service helps businesses and individuals find memorable, keyword-focused domain names for websites and online projects. Customers can browse the full inventory, search by terms or other parameters, and download a domain list for review.

SITE.su offers both outright purchases and monthly rentals. Buying a domain is completed online, with the domain transferred to the buyer’s administration. Rental gives the customer the right to configure the domain’s name servers, and the rental agreement provides a priority right to purchase it during the contract period, at a price fixed in the agreement. Rental contracts can last up to 50 months.

The marketplace displays information such as asking prices, domain age, and search-related ratings to help customers compare options. Visitors can contact the team through the Help section or online chat, ask questions about a domain, and propose a price.
