    Security

    No harmful code found in the mods we checked

    We checked 31 of its 32 mods, 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.

    Privacy

    Its mods send nothing about you

    We read the code of 31 of its 32 mods, without running it.

    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

    No sign that AI was used to make its mods

    We found no AI use from before this release (10 Aug 2026) in the 25 mods we checked.

    1 mod shows AI use only from after it, so it does not apply to the versions in this pack.

    7 mods are not checked yet.

    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.
