    About

    SeedMapper is an in-game Fabric mod for exploring and querying a configured Minecraft world seed; its seed-based features require access to the seed. It opens an explorable map of the seed and can display the same generated features in a configurable HUD minimap that updates when you change dimensions. Its locating tools can find nearby biomes, structures, chest loot matching item or enchantment conditions, copper and iron ore veins, and slime chunks, with biome and structure searches supporting all dimensions. You can highlight blocks and ore veins in the world, with raw ore blocks distinguished from other parts of a vein, and adjust the view of searches by changing the command source’s position, rotation, dimension, version, or seed. When Meteor’s version of Baritone is present, an AutoMine setting can make it mine certain blocks highlighted by SeedMapper. The mod also supports predicting future vault loot from the seed: it detects the current position in the shared loot sequence from items ejected by opening a vault, then lets you inspect future drops using either the detected sequence state or an offset.

    Libraries packed inside it change 1 more game code file: SimpleWaypoints and BetterConfig.

    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

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. No web address is written in its code. 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 29 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.
      29 latest files: the newest file for each Minecraft version and loader. The answer above is about the 11 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 3 web addresses 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 11 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.

    • Address built while the game runsThe code builds this address while the game runs: it is not written in the file.

    • 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.
