    About

    Lan UPNP uses UPnP to make a Minecraft world opened to LAN reachable by friends over the internet, so the host can share their public IP address and port for others to join. It also supports dedicated servers, where players connect using the server's IP address and port.

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

    Security

    No harmful code found

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.5.2 to 1.12.2.

    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. It contacts 2 web addresses. 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.
    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 Forge 1.5.2 to 1.6.4.

    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 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.
      6 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. 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
    • Uses folders outside the game
      Finds the Minecraft folder.
    • Looked for, not foundWe looked for these in the file and did not find them.
      Other programs, updating itself, the webcam or microphone, an AI service.

    Sends unknown data

    It has no file for a recent Minecraft version. This is about its files for Minecraft 1.5.2 to 1.12.2.

    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 6 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.

    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.
