SITE.su is an online marketplace specializing in premium domain names for businesses, projects, and individuals seeking a distinctive web address. Its catalog includes tens of thousands of domains, primarily in the .ru, .su, and .рф zones, with listings searchable by keyword, transliteration, translation, and related terms. Customers can browse the full inventory, use advanced search filters, and download domain lists with available metrics.

The marketplace offers two ways to secure a domain: immediate online purchase, with the domain transferred promptly, or rental through the assignment of the customer’s DNS servers. Some rental arrangements include a guaranteed right to buy the domain later. Listings display purchase and monthly rental prices, and may include details such as domain age and search-related ratings.

SITE.su also provides an online inquiry form for questions or price offers, along with help and chat support. The service is designed to make finding, evaluating, and acquiring relevant domain names straightforward, whether customers are ready to buy or prefer to rent first.
