    Security

    No harmful code found in its mods

    We checked all 24 mods 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.

    Privacy

    1 mod sends something about you

    We read the code of all 24 of its mods, without running it.

    WorldEditUsage data +1

    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 tool in the 24 mods we checked, and no AI content is declared for them on Modrinth.

    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, images and code history 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.
