    About

    Compressed Factory lets you fit a large room or workshop into a much smaller footprint by building a hollow Compressor multiblock that compresses the space inside it. The smallest documented Compressor, a 3×3×3 structure, creates an 11×11×11 factory, while the largest, a 15×15×15 structure, creates a 47×47×47 factory; rectangular structures are also possible, such as a 5×3×3 Compressor creating a tunnel-shaped room. A teleporter in the Compressor takes you into the factory, and you can build Compressors inside other Compressors for up to three levels of nested spaces. Item buffer blocks and an energy buffer connect the factory to the outside, with the energy buffer using Forge Energy and supporting configurable capacity and upgrades. Factories are chunkloaded by default, can be switched on or off, and can be configured to require energy to create or maintain their compressed space. Optional travel between factories at the same compression level lets you move between separate bases, while configuration also allows changes to factory scale and other buffer settings. The casing can be recolored in-game by using an opaque block on it, and the controller changes texture to indicate whether the factory is on or off.

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.12.2.

    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 1.12.2.

    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 1.12.2. See each file in Releases

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files and images 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.
