A MUD is a multiplayer real-time virtual world, usually text-based. MUDs combine elements of role-playing games, hack and slash, player versus player, interactive fiction, and online chat. Players can read or view descriptions of rooms, objects, other players, non-player characters, and actions performed in the virtual world. Players typically interact with each other and the world by typing commands that resemble a natural language.

Rent, in MUDs, is a mechanism for both enabling and limiting persistence of a player character's possessions. In the "traditional" rent paradigm, in order to keep belongings between game sessions, the player must travel to an inn and use the rent command there, and is assessed a price, in game money, for each inventory item; items that cannot be paid for are not persisted. If the player simply uses the quit command rather than rent, inventory items are not kept, and fall to the ground. Many evolutions of this approach exist: the rent command is often made to be performable anywhere rather than only at an inn, sometimes costs are removed or made negligible, and so on. At times, in MUDs where inventory is made to simply persist automatically when the player quits the game, the conceptualization of inventory persistence as "rent" is sufficiently ingrained that this is referred to as "autorent".
