SITE.su is an online marketplace for premium domain names, offering a catalogue of more than 40,000 domains in the .ru, .su and .рф zones. The service is designed for businesses and individuals seeking a memorable web address for a website, brand or personal project. Customers can browse available names, search by keywords or other parameters, and view a full catalogue online or download a list for review.

Domains are available for immediate purchase or monthly rental. Purchases are completed online with instant domain transfer, while rental works by assigning the customer’s DNS servers. Some rental arrangements include a guaranteed right to buy the domain later. Listings display prices for both options alongside details such as domain age and selected audience or search statistics. Customers who wish to negotiate can submit a question or offer a price through the site. SITE.su also provides account access, help, and online chat for customer inquiries.
