    About

    Compendium is a material library and building-customization mod that lets players use materials in step-by-step crafting and create stylized blocks from combinations of materials and parts. Its Index records information about materials and their uses, and can be extended with a JSON file and graphics, or by drawing on materials and graphics supplied by other mods; other mods can also bundle Index files for automatic pickup. The included materials cover wood types such as oak, spruce, birch, cherry, mangrove, acacia and dark oak, plus iron, copper, gold, netherite and all 16 wool colors. Workstations include an expandable Workbench with a crafting grid that grows from 3×3 to 5×5, a Hammering Station for crushing materials such as stone into cobblestone and gravel into sand, and a Sawbuck for chopping logs into smaller pieces and sawing them into planks. A Cosmetic Toolbox lets players change the shape and texture of stylable blocks, whose separate parts can use different materials from the Index and be styled independently. Examples of the eight included multi-material block types are chairs, tables, clothed tables, beds, windows, Fancy Fences and shingles or caps; their parts draw on wood, textile, glass and metal material types as appropriate. The mod also adds tools with distinct uses: the Hammer mines a 3×3 area as a pickaxe, the Saw strips logs or fells whole trees, and the Prybar removes blocks marked as pryable. The Zweihander is a large sword whose right-click swing damages and knocks back nearby enemies, briefly weakening its wielder. The gallery illustrates the depth of chair customization, including 48 back styles, 8 seat styles and 31 leg styles, alongside examples of furnished rooms, fences and a workshop equipped with Compendium workstations.

    Source code

    Security

    No harmful code found

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

    What it can do on your computer

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. No web address is written in its code. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them.

    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 · The latest file checked, last on 15 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.
      5 latest files: the newest file for each Minecraft version and loader. The answer above is about the one for a recent version. 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
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, other programs, 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 · Its one file 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 its one file, for recent Minecraft versions. See each file in Releases

    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.
