    About

    Ductwork adds a three-block item-distribution network for moving items around the world, designed to offer flexible, space- and resource-efficient alternatives to hopper networks while remaining reliable in systems that mix ducts and hoppers. Ducts carry items from up to five adjacent input blocks toward their output, while collectors pull items from an inventory or open space behind them and can be oriented to collect from different sides. Dampers connect items from behind to the output in front and can be locked with redstone; when closed, they also allow items to be extracted through their sides, enabling signal-controlled diversion. Together, the blocks can be used in practical builds such as compact item sorters, redstone damper clocks, selective composters, and distributors that split items among as many as five destinations. Blocks can be reoriented without being broken, and an optional orientation indicator resource pack adds arrows showing the direction items will travel. A server option can restrict the blocks to hopper-like behavior, while other configuration options include cheaper crafting recipes and placing ducts directly against one another.

    Written from Modrinth . How we write it

    In-game changes

    Changes the game's code in 3 areas: PlayerChanges 1 game code file in this area: your character: movement, abilities, hunger and controls., Blocks and fluidsChanges 1 game code file in this area: how blocks, fluids and redstone work. and Game data and resourcesChanges 1 game code file in this area: recipes, tags, advancements, language files and other game data..

    Adds 3 blocks: Collector, Damper and Duct; 6 recipes.

    Counted from the names and data files in the mod, so the list may not be complete.

    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

    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 · All 18 latest files 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.
      18 latest files: the newest file for each Minecraft version and loader. The answer above is about the 9 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.
    • 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

    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 9 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 9 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 so far that AI was used to make it

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

    We have not read its code history 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.
