    About

    MapSyncer for Xaero's World Map transfers server-side explored map regions into clients’ Xaero’s World Map, helping players joining an already explored or pre-generated world see its map without having to explore the same areas again. It supports the Overworld, Nether, End, and modded dimensions, with configurable surface and cave-layer scans, including scans of all layers or selected heights. The mod can automatically synchronize maps when players join and, when the server is configured for periodic or scheduled cache updates, keep clients updated while they play; manual synchronization is also available. Transfers compare region hashes and timestamps to send changed data, prioritize regions near the player, and can resume after an interruption; bandwidth limits and streaming delivery help control transfer and loading behavior. Servers can generate map caches for all dimensions, a selected dimension, or a single region, inspect generation progress, and configure periodic or scheduled cache regeneration. The mod works with dedicated servers and integrated servers used for LAN play, reusing the host’s Xaero map directory in the latter case, and the server does not need Xaero’s World Map installed.

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

    Security

    No harmful code found

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

    What it can do on your computer

    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 Fabric 1.20 to 26.1.2.
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 2 files 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 10 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.
      10 latest files: the newest file for each Minecraft version and loader. All 10 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.
      The internet, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    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
    • 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.
