Licenses & Attributions
Last updated: September 3, 2026
This page covers two separate obligations: the attribution required for the openly licensed game-system content built into DMRealm, and the notices for the open-source software the DMRealm web application is built from.
Content licenses
DMRealm includes some built-in game-system reference content — item and creature catalogs and stat-block schemas — derived from openly licensed sources. This section provides the attribution those licenses require, in addition to the notice shown wherever the content appears in the app and in every export. DMRealm is an independent product and is not affiliated with, endorsed by, or sponsored by Wizards of the Coast, the Dungeons & Dragons brand, or any other tabletop-RPG publisher.
