    • Mana Bar in game

    About

    Koala Lib is a shared library that provides reusable systems for mods, including configuration support, update checking, render-layer post-processing shader registration, and customizable vanilla items such as shields and bundles. Its optional Magic Bar gives compatible mods a mana meter that can regenerate when the player is fully fed and can be replenished or depleted by items. The library also supplies reusable foundations for mana upgrades and downgrades, consumables and magic foods, mana-cost items, and transformation items that can convert blocks, creatures, or dropped items into other forms. Mods can use its mana mechanics to manage current and maximum mana, passive regeneration, and items whose effects depend on mana cost.

    Written from Modrinth and the GitHub README . How we write it

    Changes the game's code in 9 areas, as a library other mods build on: Rendering and graphicsChanges 5 game code files in this area: drawing mobs, items, particles and textures on screen., Mobs and their behaviorChanges 5 game code files in this area: mobs, animals, villagers, projectiles and how they move and act., Blocks and fluidsChanges 5 game code files in this area: how blocks, fluids and redstone work., User interfaceChanges 3 game code files in this area: menus, screens, tooltips, the chat window and the in-game overlay., PlayerChanges 2 game code files in this area: your character: movement, abilities, hunger and controls., Inventory and itemsChanges 2 game code files in this area: items, chests and other containers, crafting and enchanting., World renderingChanges 1 game code file in this area: drawing the terrain, sky, clouds and weather., Networking and multiplayerChanges 1 game code file in this area: connections, the server list and what is sent between your game and a server. and Game data and resourcesChanges 1 game code file in this area: recipes, tags, advancements, language files and other game data..

    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. Only in its files for Fabric 1.21 to 1.21.1.
    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. 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 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.
      3 latest files: the newest file for each Minecraft version and loader. All 3 are 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.

    Privacy

    Sends unknown data

    Sent to an address built while the game runs.

    Only some of its files send unknown data.

    We found this in its code, read without running it.

    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 3 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 3 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.
      Checks for a new version of the mod.Explained by AI (may be wrong)Explained by an AI from the code. May be wrong.
      Unknown data
    • 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, images and sounds 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.
