    About

    MixinBooter provides a shared Mixin library that lets mods use mixins on Minecraft versions from 1.8 through 1.12.2. It registers mixin configurations from a mod’s manifest, either directly through the MixinConfigs attribute or programmatically through a MixinConnector. For mod developers, it also offers configuration options to blacklist mixin configs and enable debugging, plus dedicated logs that can trace class loading and tools for discovering which mods are present.

    Written from Modrinth . How we write it

    In-game changes

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8 to 1.12.2.

    Changes the game's code in 1 area, as a library other mods build on: Other game codeChanges 1 game code file in this area: game code that is not in one of the areas above..

    Adds no new blocks, items or other content.

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

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8 to 1.12.2.

    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. 1 file in your config folder.
    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Found in the mod's own code and in code libraries built into it. See Privacy

    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
    • 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.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends about you

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.8 to 1.12.2.

    We read its code without running it: it contacts 1 web address while you play.

    Like any connection, each address it contacts sees your IP address.

    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 1.8 to 1.12.2. See each file in Releases
    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.
      Purpose not known.
    • 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.

    Known conflicts

    These projects do not work together with MixinBooter: their authors or MixinBooter's author say so. If you install both, the game can crash or some features can stop working. Some of them do the same job as MixinBooter, so you only need one.
