No harmful code found in the projects we checked
We checked 273 of its 276 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.

2 mods send something about you
We read the code of 261 of its 264 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.21 mods
- Crash reports or usage dataTheir author declares crash reports or usage data on Modrinth, or such a service is named in their files. Reading their code did not show it.2 mods
- Send nothingTheir code contacts no web address.238 mods
- Not read yetWe have not read their code yet.3 mods
AI
AI named in 21 of the 209 mods we checked
We found an AI tool named in them, or their authors declare AI content.
1 other mod shows AI use only from after this release (24 Oct 2026), so it does not apply to the versions in this pack.
55 mods are not checked yet.

We looked for AI tools in its texts and found none.
We have not read its files and images 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.
