SITE.su is an online marketplace for buying and renting domain names, with a catalog of more than 40,000 listings across the .ru, .su and .рф extensions. The service helps businesses and individuals find keyword-based domains for websites, brands and other online projects. Visitors can browse the full catalog, search by one or more terms, or use advanced filters to explore relevant options. Each listing provides pricing for purchase and rental, with additional details such as domain age and available rating or search statistics.

Customers can buy selected domains online, with the site describing the purchase process as providing immediate domain transfer. Rental is available through the assignment of the customer’s DNS servers, and some offers include a guaranteed right to buy the domain later. The marketplace also supports enquiries and price proposals for individual listings. Users can download a spreadsheet of the domain catalog, while the Help section offers contact information and online chat.
