    About

    Heracles is a questing mod for modpack makers, who can create completable quest trees and distribute them for players to follow. Quests can be organized into groups and connected by dependencies, so completing one quest can unlock the next. Quest descriptions are customizable and can include task and reward details, while a task screen shows each quest’s objectives and how much progress has been made on them.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Changes the game's code in 6 areas, as a library other mods build on: PlayerChanges 3 game code files in this area: your character: movement, abilities, hunger and controls., User interfaceChanges 3 game code files in this area: menus, screens, tooltips, the chat window and the in-game overlay., Game data and resourcesChanges 2 game code files in this area: recipes, tags, advancements, language files and other game data., Server and world logicChanges 2 game code files in this area: the world, commands, scoreboards, saved data and game rules., Game optionsChanges 1 game code file in this area: settings, key bindings and the option screens. and Inventory and itemsChanges 1 game code file in this area: items, chests and other containers, crafting and enchanting..

    Adds 1 block: Barrier; 1 item: Quest Book; 1 sound: Quest Complete; 1 key binding: Open Quests.

    Counted from the names and data files in the mod, so the list may not be complete.

    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

    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 1.21.1; NeoForge 1.21.1. 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 6 latest files checked, last on 19 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.
      6 latest files: the newest file for each Minecraft version and loader. The answer above is about the 4 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

    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 4 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 4 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
