The marketplace also offers rental agreements with a guaranteed right to buy, giving customers a path from temporary use to ownership. Listings display purchase and monthly rental prices, and may include information such as domain age and rating.

Visitors can search by one or more words, explore suggested synonyms or translated terms, and use advanced search to narrow results.
