Is there a character builder for Baldur's Gate 3?

Direct answer: Baldur's Gate 3 does not rely on an official external character builder; you create and customize your character directly in-game, including fully customizable Origin options like The Dark Urge. This in-game customization is highlighted by official announcements about Origin characters and customization options. For planning ahead of or alongside in-game choices, however, there are several third-party tools you can use to map out races, classes, spells, and feats, often with shareable links and build databases. The Dark Urge and related customization options are an official example of in-game personalization.
