The official AddonScript specification is available in the master branch of the addonscript-spec repository and on

What is AddonScript?

AddonScript is a format to distribute Minecraft addons. An addon could be anything, which is installed into the Minecraft game, like a mod, modpack, modloader, texturepack or even a world. AddonScript can be used for example to define how addons are installed, or to specify dependencies for addons. This way, addon creators just have to publish the AddonScript file for their addon and let AddonScript compatible tools (for example launchers) install them.

The values of AddonScript


AddonScript can be used by everyone. There is no company or economic interest behind AddonScript. It is intended to be an open standard, which can be implemented by anyone who likes to. Anyone can contribute ideas to the AddonScript specification.


AddonScript depends on nothing, except Minecraft itself (and Java). This means that the specification does not depend on existing APIs and formats like Curseforge. It also does not reference any specific modloader like Forge or Fabric, instead they are themselves addons, which can be defined using AddonScript. This means, that AddonScript is not bound to a specific set of modloaders, instead you can use any modloader.


AddonScript is not bound to any specific use case like just for modpacks or just for mods. Instead it is considered to be a universal format, which can handle anything, that is installed into the Minecraft game. AddonScript can handle modloaders, mods, modpacks, texturepacks and even worlds and maybe other things as well.
