    About

    Debugify fixes more than 70 bugs reported in Minecraft’s bug tracker, focusing on bug fixes rather than adding unrelated quality-of-life features or content. Its fixes cover both client and server behavior, including examples such as saved fullscreen state, chunk saving, entity-collision performance, tooltip display, and the growth of two-by-two jungle or spruce sapling arrangements. Debugify also incorporates fixes associated with projects such as Shift-Scroll Fix, ForgetMeChunk, ChunkSavingFix, No Telemetry, Title Fix Mod, and Skeleton Aiming Fix; those projects are not necessarily incompatible with it and may still be used for additional features. Players can choose which fixes to enable through a configuration GUI or config file, and modpack makers can configure newly added fixes to default to off.

    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. 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. Only in its files for Fabric 1.20.1 to 1.21.8. 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 · All 28 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.
      28 latest files: the newest file for each Minecraft version and loader. The answer above is about the 10 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.
      Folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
    • Modrinth and CurseForgeA release with a different file on Modrinth and on CurseForge, whose code is not the same. Each file is checked on its own. Nothing is blocked.
      Minecraft 1.19 · Fabric, Quilt · release 2.0.0 · 9 Jun 2022: Modrinth debugify-2.0.0-fabric-1.19.jar, CurseForge debugify-2.0.0-fabric-1.19.jar. 2 classes changed, 5 classes only in the CurseForge file, in dev.isxander.debugify: ConfigGuiHelper, ArmorStandEntityRendererMixin, DebugifyLightProvider (CurseForge only), ClientPlayNetworkHandlerMixin (CurseForge only), LivingEntityRendererMixin (CurseForge only), HandledScreenMixin (CurseForge only), StriderEntityMixin (CurseForge only).
      code differs in 1 release

    Privacy

    We found nothing it sends about you

    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 · All 10 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 10 files, for recent Minecraft versions. See each file in Releases
    • bugs.mojang.com
      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.
