    Mod grades

    How grades work

    Modpacks get no grade of their own, so we show the grades of its mods. Of its 256 graded mods, 228 are graded A or B, 28 C and none D to F. Its last update came out 3 months ago, for Minecraft 1.21.1. See the mods

    Content of this pack252 of 256 checked

    No harmful code found in the projects we checked

    We checked 252 of its 256 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.

    7 mods send something about you

    We read the code of 247 of its 253 mods, without running it.

    Entity CullingCrash reportsCollectivePlayer IDNot Enough AnimationsCrash reportssparkUnknown dataCrash AssistantUnknown dataImmersive MelodiesUnknown dataImmersive PaintingsWhat you type

    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.

    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.
