SITE.su is an online marketplace specializing in premium domain names for individuals and businesses developing web projects. Its catalog features more than 39,000 domains, including keyword-based and other memorable names in the .ru, .su, and .рф zones. Customers can browse available listings, search by words or other parameters, and review details such as prices, domain age, and selected rating or traffic indicators.

The marketplace offers two ways to obtain a domain: immediate online purchase, with the domain transferred to the buyer, or rental, which is arranged by assigning the renter’s DNS servers. Some rental arrangements include a guaranteed right to purchase the domain. Listings display purchase prices and monthly rental rates, and interested customers can submit a question or propose a price through the site.

SITE.su also provides access to a full domain list, including a downloadable spreadsheet, and offers help and online chat through its support section. The service is designed to make finding, comparing, and acquiring domain names straightforward, whether customers prefer to buy outright or rent first.
