    About

    Terra is a world-generation platform for Minecraft that lets creators customize terrain generation through an extensible voxel API and an integrated configuration system. Its platform implementations connect the API to supported environments, while an addon loader lets addons provide generation features independently of any one platform; core addons supply a standard configuration schema and a preinstalled Overworld pack. Players can use the default Overworld pack, which provides vanilla resources, or load other configuration packs to change the worlds Terra generates. Community packs span several distinct world concepts: Tartarus adds Nether biomes, ReimagEND reshapes the End with new biomes and terrain, Hydraxia turns the world into a winter landscape, and SkyLands creates floating islands with biomes and structures. Other examples include Substratum’s underground world and caves, VoidWorld’s void setting, Terra Backrooms’ Backrooms-like levels, and Origen’s exotic Overworld biomes. Pack authors can build configurations from scratch or modify existing packs, using tools for terrain expressions, layered terrain, noise, image-based configuration, and TerraScript; the API also supports addon development such as registering structures and responding to events. Terra supports Fabric, Forge, Quilt, and Bukkit-based servers, and on supported servers it can generate worlds that Vanilla clients can join without installing Terra.

    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. Only in its files for Fabric 1.21.4 to 1.21.8; Paper 1.21.1 to 1.21.8.Not a Warning: we read its code and found no code downloaded over http or run without a check.
    Uses folders outside the game
    It can read or write files outside your Minecraft folder, on the rest of your computer. Found: the temporary files folder and your user folder.
    Starts other programs
    It can start another program on your computer, for example to open a link in your browser. Found in Terra-language-yaml, a packed file the mod does not list.
    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 the mod's own code and in 4 packed files the mod does not list. 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 31 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.
      31 latest files: the newest file for each Minecraft version and loader. The answer above is about the 12 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.
    • Uses folders outside the game
      Uses the temporary files folder.
    • Starts other programs
      Can run system commands.
    • Looked for, not foundWe looked for these in the file and did not find them.
      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.

    Its files for older Minecraft versions (1.13 to 1.18.2) also send usage statistics.

    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 12 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 12 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.
