    Mod grades

    How grades work

    Modpacks get no grade of their own, so we show the grades of its mods. Of its 436 graded mods, 367 are graded A or B, 64 C and 5 D to F. Its last update came out 8 weeks ago, for Minecraft 1.21.1. See the mods

    Content of this pack432 of 436 checked

    The mods of its newest release (Minecraft 1.21.1 · NeoForge, 29 Aug 2026). Each check result is for the latest files of that mod, which may not be the version in this pack.

    No harmful code found in the projects we checked

    We checked 432 of its 436 projects, without running them.

    We have not checked the files in the pack itself yet (settings, scripts).

    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.

    9 mods send something about you

    We read the code of 417 of its 418 mods, without running it.

    Entity CullingCrash reportssparkData we could not identifyLet Me DespawnUsage dataCrash AssistantData we could not identifyPneumaticCraft: RepressurizedCrash reportsPolyLibCrash reportsObservableData we could not identifyNeoAuthData we could not identifyCreate: Deployer APIPlayer ID

    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 named in 8 of the 344 mods we checked

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

    20 other mods show AI use only from after this release (29 Aug 2026), so it does not apply to the versions in this pack.

    74 mods are not checked yet.

    2 mods can use AI in the game.

    Made with AI: not checked yet

    We have not looked for AI tools in the pack itself 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.
