Mods/Forge

Minecraft Forge is a free, open-source modding API and loader designed to simplify compatibility between community-created game mods in Minecraft: Java Edition. The end-user (player) must play the version of Minecraft that Forge was downloaded for before it can be used. For example, Forge 1.12 will need the 1.12 version of Minecraft in order to run correctly. Forge can then be used from the Play drop-down in the Minecraft launcher.

Forge mods
The majority of modern mods use Forge in order to be added to vanilla Minecraft, some mods that support Forge are listed on its website.

Forge mods only work with Forge. Forge processes mods differently than Modloader, so only certain mods can work with the two.

The user may want to see if the mod they want supports Forge.
