Embodiments relate to systems, devices, computer-readable media, and computer-implemented methods for generating domain name suggestions by receiving an input string via a user interface, determining an alternative of the input string, determining affixes of the input string, determining top level domains associated with the input string, determining registration availability of domain names including one-step string sequences from the input string based on the alternative input string, the affixes of the input string, and the top level domains associated with the input string, and generating a display for the user interface, where the display includes: the input string, the alternative of the input string, the affixes of the input string, and the top level domains associated with the input string; and indications of the registration availability of the domains names including the one-step string sequences.
