Minecraft wiki entry for Add-on, associated text: Add-ons are also often used in maps for the Minecraft Marketplace. All add-ons needed for the map are automatically downloaded and integrated into the world after purchase when downloading. The add-ons can be used in other maps, but it always depends on whether or not the developer allows this. It is also to be noted that the Marketplace is the only official add-on market, but there are add-on websites that have community-made add-ons by non-Minecraft partner developers, and that those add-ons are not just piracy versions of existing Marketplace packs, but original work. Third-party add-on are nevertheless not available on PlayStation 4 and Nintendo Switch.
