This author published many projects at once on Modrinth: up to 10 projects published within 2 weeks. 43 of the author's 49 projects have only one release and no source code link. A series of small add-ons is often published this way. It does not change the grade.
About
One Block ModPack builds on the OneBlock survival concept, starting players on a tiny island in the void with a single regenerating block as their source of materials. Breaking the block cycles through more than 40 biomes and resource pools, with access to new materials from the Nether and End as players progress; surprise events, friendly mobs, and increasingly challenging monster waves add variety to the journey. The pack also includes performance-focused additions intended to improve frame rates and reduce lag while supporting smoother, more stable play. It supports singleplayer and multiplayer, where each player can have an independent island, and optional datapacks can further customize the experience with options such as void dimensions or a hardcore start without an island.

No harmful code found in its mods
We checked all 12 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 projects12 mods
- Files in the pack itselfNo files in the pack itself: it only lists the projects to download.
- Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.Nothing declared about your system outside the game.

2 mods send something about you
We read the code of all 12 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.4 mods
- Send nothingTheir code contacts no web address.6 mods
AI
AI used in 2 of the 12 mods we checked
We found an AI tool in them, or their authors declared AI content.
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 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.No AI content declared.
