About
GregFactory Sky is a technology-focused skyblock modpack built around GregTech-Modern, starting players on a small island with only a tree and some dirt. Players gather resources through different means, expand their island, advance through a substantial but moderately difficult technology progression, and automate production. The pack keeps GregTech-Modern close to its original form, while recipes from other mods are adjusted to fit its progression; those additional mods are kept to a moderate, complementary selection. It also adds several custom machines and multiblock structures to discover, and late-game progression offers a way to create creative-mode items with the help of mysterious powers.

Security
No harmful code found in its mods
We checked all 73 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.
How we checked
- Its projects73 mods
- Files in the pack itself178 settings files, 87 scripts, 34 other files, 1 mod jar.
Privacy
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.5 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.65 mods
AI
AI used in 6 of the 64 mods we checked
We found an AI tool in them, or their authors declared AI content.
9 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.
- Code historyThe public code on GitHub: who made each change, credit lines such as "Co-authored-by", and its files.Not read yet
- 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
