īy 2017, Wizards of the Coast's D&D Beyond site for Dungeons & Dragons 5th edition announced the inclusion of a homebrew section allowing users to post fan-made content. In November 2007, fan-made repository D&D Wiki updated its front page to use the term 'homebrew' in reference to all fan-made D&D content, including classes, feats and deities. In an article dated July 2006, designer Mike Mearls used the word 'homebrew' in a broader sense to refer to monster design. The usage of the term 'homebrew' evolved from fan-made worlds to fan-made game material in general. Wizards of the Coast also used the term in the context of campaign worlds in articles on the official Dungeons & Dragons website in 2005.

In August 2003, the Wizards Community Boards had a forum named Homebrew for the purpose of home-made campaign worlds, suggesting that at that time the community used this word specifically to refer to campaign settings. The term 'homebrew' has been used by the D&D fan community at least as far back as 2003, where it was used to refer to to a home-made D&D campaign setting in contrast to an official published world: 'As someone who has not until recently learned much about Dragonlance, I'm excited to see what it can offer my homebrew campaign.' - kexizzoc87, 2003

The term entered metaphorical use for anyone who produces hobbyist versions of products which are normally produced only commercially, such as video games for consoles.
