Security
No harmful code found in the projects we checked
We checked 83 of its 84 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.
How we checked

Privacy
6 mods send something about you
We read the code of all 83 of its 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.
How we checked
- Go online onlyTheir code contacts a web address, for example to check for updates. We found nothing it sends about you.14 mods
- Send nothingTheir code contacts no web address.63 mods
AI
No sign that AI was used to make its mods
We found no AI tool in the 44 mods we checked, and no AI content is declared for them on Modrinth.
39 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.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
- Its filesFiles that AI coding tools leave behind (like AGENTS.md), and the texts inside the files you download.Not read yet
- Images in its filesHidden data in the images of the files you download, where AI image tools write their name and settings.Not read yet
