    About

    KAllFix is a server-capable optimization and compatibility mod that targets performance problems, crashes, and other issues caused by interactions among mods. It combines KAllFix’s targeted fixes with K_multi_threading, which can parallelize block and block-entity ticks, entity and dimension work, and, when enabled, player packet handling and login tasks. Its fixes and optimizations cover concrete cases such as AE2’s game computations, chicken-coop AI and excessive packet sending in [Let’s Do] Farm & Charm, entity-heavy L_Ender’s Cataclysm servers with MineColonies, Alex’s Caves magnetic-field performance, and compatibility between Biolith and some MCreator world-generation mods. It also addresses performance or compatibility issues in mods and systems including Create: FluidLogistic, Create: Diesel Generators, Atmospheric, Upgraded Core, Upgraded Additional Trims, Apotheosis, and Create: Connected. Many features are controlled through JVM startup parameters rather than a regular configuration file, including options to set thread-pool limits, disable multithreading, adjust selected fixes, and enable packet optimization on both client and server. Multithreading is enabled by default on servers, while client-side features can also be enabled; the project warns that setting a thread limit is important because world generation may otherwise freeze.

    Security

    No harmful code found

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

    What it can do on your computer

    Can update itself
    It can add or replace files in your mods folder, for example to update itself.
    Can download and run new code
    The same part of the code can download data and run it as code. Auto-updaters do this, and so does malware. Found in K_multi_threading, a packed file the mod does not list.Not a Warning: we read its code and found no code downloaded over http or run without a check.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Only in its files for NeoForge 1.21 to 1.21.1.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 15 files 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 K_multi_threading, a packed file the mod does not list. 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 3 latest files checked, last on 18 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.
      3 latest files: the newest file for each Minecraft version and loader. The answer above is about the 2 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.
    • Uses folders outside the game
      Uses the temporary files folder.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Other programs, the webcam or microphone, an AI service.

    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 · Both 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 both files, for recent Minecraft versions. 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 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.

    How we checked · 5 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.
