    About

    Ledger is a server-side logging mod that helps Minecraft server moderators investigate world changes and recover from unwanted activity. It records hundreds of kinds of in-game events, from block placement to silverfish infestations, and lets moderators search the history by player, action, time, or object. Moderators can inspect the logs for a particular location, browse or page through search results, and use filters to narrow results by such things as source, object, action type, or dimension. Rollback tools can undo selected logged actions, while restore can reverse a rollback for supported block, item, and entity changes.

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

    In-game changes

    Changes the game's code in 7 areas, as a library other mods build on: Blocks and fluidsChanges 55 game code files in this area: how blocks, fluids and redstone work., Mobs and their behaviorChanges 22 game code files in this area: mobs, animals, villagers, projectiles and how they move and act., Inventory and itemsChanges 16 game code files in this area: items, chests and other containers, crafting and enchanting., Server and world logicChanges 4 game code files in this area: the world, commands, scoreboards, saved data and game rules., Game coreChanges 3 game code files in this area: the main loop, lighting and other code the whole game uses., PlayerChanges 2 game code files in this area: your character: movement, abilities, hunger and controls. and Networking and multiplayerChanges 1 game code file in this area: connections, the server list and what is sent between your game and a server..

    Libraries packed inside it change 14 more game code files: Packet Tweaker and Server Translations API.

    Adds no new blocks, items or other content.

    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

    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 javassist, a library it includes and in reflections, a library it includes.Not a Warning: we read its code and found no code downloaded over http or run without a check.
    Accepts connections from other computers
    It can accept connections from other computers. Found in javassist, a library it includes.
    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Found in sqlite-jdbc, a library it includes.
    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 8 libraries it includes. See Privacy
    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.

    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 23 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.
      23 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.
    • Starts other programs
      Can run system commands.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Folders outside the game, updating itself, 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 · 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
    • 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 Ledger: their authors or Ledger'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 Ledger, so you only need one.
