SITE.su is an online marketplace specializing in premium domain names, offering a catalog of more than 40,000 domains across the .ru, .su, and .рф zones. Customers can browse available names, search by keyword or other parameters, and view a downloadable full catalog. The service supports both immediate online purchases and monthly rentals, making domain names accessible to businesses and project owners considering different levels of commitment.

A purchase transfers administration rights to the buyer. Rental provides the right to change the domain’s name server settings and includes a contractual priority right to buy the domain during the rental term, with the purchase price fixed in the agreement. Rental contracts can last up to 50 months. Visitors can submit questions or price offers through the site, while its Help section provides access to contact information and online chat. SITE.su presents domain details such as price, age, and search-related indicators to help users assess potential options. Its offering is focused on domain acquisition and rental rather than website hosting or business services.
