SITE.su is an online marketplace for premium domain names, offering a catalog of around 40,000 domains in the .ru, .su, and .рф zones. The service helps businesses and individuals find a domain for a website, brand, or personal project, with searchable listings organized by matching words, transliterations, synonyms, and translations. Customers can browse the full catalog, use advanced search options, or download a domain list in Excel format.

SITE.su offers two ways to obtain a domain: immediate online purchase, with the domain transferred after payment, or monthly rental, arranged by assigning the customer’s DNS servers. Some rental agreements include a guaranteed option to buy the domain later. Listings show prices for both purchase and rental, and the site provides a contact form for questions or price offers, along with help and online chat. By bringing a large selection of domain names and flexible acquisition options together, SITE.su makes it easier to secure a suitable web address.
