    About

    FTB Team Bases manages team-linked player bases, replacing earlier FTB base-management mods with configurable ways to create and house each team’s base. Server owners and pack makers define base templates in datapacks, choosing whether each base lives in a shared dimension or a private dimension created for that base. Templates can build bases by relocating pregenerated region files, pasting a single NBT structure, generating structures through Minecraft’s jigsaw system, or using prebuilt structures from the world-generation registry. Region templates can support very large bases spanning one or more 512-by-512-block regions; relocation is intended for void dimensions or non-void dimensions with a fixed seed so the terrain aligns with world generation. A base is paired with an FTB Teams team: creating one creates the team, joining an existing team sends players to its base, and leaving or disbanding the team returns players to the lobby while the base is archived when the team is disbanded. Players can travel between the lobby and their team’s base, while a configurable portal block in the lobby sends team members to their base and opens base selection for players without a team. The mod can also create an initial lobby for new players, using either a placed NBT structure or pregenerated regions, and supports configuring the lobby’s dimension and spawn location.

    Security

    No harmful code found

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

    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 3 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.
      3 latest files: the newest file for each Minecraft version and loader. All 3 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
    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, 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 3 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 3 files, for recent Minecraft versions. See each file in Releases

    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 · 5 places read
