    Mod grades

    How grades work

    Modpacks get no grade of their own, so we show the grades of its mods. Of its 254 graded mods, 218 are graded A or B, 32 C and 4 D to F. Its last update came out 2 days ago, for Minecraft 1.21.1. See the mods

    Content of this pack252 of 254 checked

    The mods of its newest release (Minecraft 1.21.1 · NeoForge, 22 Oct 2026). Each check result is for the latest files of that mod, which may not be the version in this pack.

    Security

    No harmful code found in the projects we checked

    We checked 252 of its 254 projects and the files in the pack itself, without running them.

    Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.

    6 mods send something about you

    We read the code of 250 of its 253 mods, without running it.

    Entity CullingCrash reportssparkUnknown data3D Skin LayersCrash reportsPolyLibCrash reportsObservableUnknown dataRTS building: Build From AboveText to an AI

    Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    AI

    AI used in 21 of the 191 mods we checked

    We found an AI tool in them, or their authors declared AI content.

    62 mods are not checked yet.

    1 mod can use AI in the game.

    No sign so far that AI was used to make the pack itself

    We looked for AI tools in its texts and found none.

    We have not read its files and images yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
