SITE.su is an online marketplace for domain names, offering a catalog of more than 40,000 domains, including keyword domains in the .ru, .su, and .рф zones. Customers can browse available names and choose between immediate online purchase and rental. Purchases are completed online with prompt domain transfer, while rental works by assigning the customer’s DNS servers; some rental offers include a guaranteed right to buy the domain later.

The marketplace provides search tools for finding domains by one or more words or topics, as well as an expanded search for filtering options. Visitors can view the full domain list, download a catalog in Excel, and review details such as prices, domain age, ratings, and selected search statistics. For customers interested in negotiating or proposing a different price, the site offers a question form. Help and contact information, along with an online chat, are available through the support section. SITE.su serves individuals and businesses seeking memorable web addresses for websites and online projects.
