    About

    Expandable Backpacks adds customizable backpacks that begin with one storage slot and can be expanded to as many as 54 by adding obsidian leather in the upgrade inventory. Backpacks can be renamed, dyed with vanilla dyes, and fitted with up to three compartments that add specialized functions. Compartments include Soulbound, which preserves the backpack and its contents on death; Pickup, which directs items already stored in the backpack into it when collected; and Empty, which transfers its contents to an inventory block. Other compartments let backpacks hold other backpacks, destroy stored items, improve armor protection, swap their first nine slots with the hotbar, draw arrows for bow shots, or provide ender-chest and crafting-table interfaces. The Tank compartment stores up to eight buckets of one liquid and lets players store or place liquid through the backpack. Sending can transfer the backpack's contents to a selected inventory block, while Guarded makes unauthorized opening attempts damage and slow the player and notifies the owner. Owners can share access with other players and switch backpacks between private access for owners and public access for everyone. A separate backpack slot inventory provides a place to keep a backpack without using the chestplate slot or a regular inventory slot.

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.9.4 to 1.10.2.

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

    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 16 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.
      1 latest file. It is not for a recent Minecraft version, so the answer above is about it. 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.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.9.4 to 1.10.2.

    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 Minecraft 1.9.4 to 1.10.2. See each file in Releases

    AI

    No sign so far that AI was used to make it

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

    We have not read its changelogs yet.

    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.
