    About

    Fragmentum is a lightweight shared framework for Obscuria Collection mods, providing a multi-loader architecture and tools that help those mods avoid loader-specific code; it does not add gameplay content by itself. Its Fragmentum Layer also lets you place your own global datapack content, such as recipes, loot tables, tags, and structures, in a configuration folder, while resource files such as textures, models, and languages can be added there as well. The layer assembles these files into virtual resource and data packs that apply across worlds, with data changes refreshed using /reload and asset changes using the resource reload shortcut. It is intended as a convenient way to add personal global content and overrides, not to load third-party zipped packs or replace full resource and datapacks.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 6 areas, as a library other mods build on: Game data and resourcesChanges 2 game code files in this area: recipes, tags, advancements, language files and other game data., User interfaceChanges 2 game code files in this area: menus, screens, tooltips, the chat window and the in-game overlay., Game coreChanges 1 game code file in this area: the main loop, lighting and other code the whole game uses., Server and world logicChanges 1 game code file in this area: the world, commands, scoreboards, saved data and game rules., PlayerChanges 1 game code file in this area: your character: movement, abilities, hunger and controls. and Other game codeChanges 1 game code file in this area: game code that is not in one of the areas above..

    Libraries packed inside it change 4 more game code files: YetAnotherConfigLib and Forge Config API Port.

    Adds no new blocks, items or other content.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    What it can do on your computer

    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Only in its files for Fabric 1.20.1 to 26.1.2; NeoForge 1.21.1 to 26.1.2; Forge 1.20.1; Quilt 1.20.1 to 1.21.1.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for Fabric 1.20.1 to 26.1.2; NeoForge 1.21.1 to 26.1.2; Forge 1.20.1; Quilt 1.20.1 to 1.21.1.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.20.1 to 26.1.2; NeoForge 1.21.1 to 26.1.2; Forge 1.20.1; Quilt 1.20.1 to 1.21.1. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. Only in its files for Fabric 1.20.1 to 26.1.2; NeoForge 1.21.1 to 26.1.2; Forge 1.20.1; Quilt 1.20.1 to 1.21.1.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · All 11 latest files checked, last on 17 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      11 latest files: the newest file for each Minecraft version and loader. All 11 are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.
      Read without running it
    • 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.
    • Starts other programs
      Purpose not known.
    • Uses folders outside the game
      Uses the temporary files folder.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: 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 · All 11 files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of all 11 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and code history and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    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 · 6 places read
    • 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.
