    About

    Katters Structures expands vanilla-style exploration with more than 30 structures, using only vanilla blocks and requiring no additional dependencies. Its settlements include cherry, jungle, swamp, ocean, underground, sky, mesa, birch and pillager villages, alongside ruined villages and mountain, ocean and desert villager statues. Other discoveries range from large birch, dark oak and cherry trees, windmills, graveyards, witch circles and shroom caves to desert, sky and improved vanilla dungeons, four mini-dungeons, an armory, a spider den, trader outposts and a magic tower. Further structures include the Skyrtle, Deep Blue labs and lab ruins, a Deep Blue city, Skyhold, ocean ships, sky decor, fossils and Far Watch. The project also adds the Deep Blue dimension, where players can encounter bosses including Raj Raksha, Tenkū Mizu Gami, Arachne, Magus Theron and Rústa. Exploration and combat are complemented by new enchantments, spells, random totems, and more than 50 story books told from the perspectives of villagers and other characters. Players can adjust selected features through in-game controls, including options to disable boss activity, boss bars, custom models or access to the Deep Blue.

    Written from Modrinth . How we write it

    In-game changes

    Does not change the game's code directly.

    Adds 3 biomes, 1 dimension, 41 structures, 13 enchantments, 1 recipe, 103 advancements and 168 loot tables.

    Counted from the names and data files in the mod, so the list may not be complete.

    Replaces 18 of vanilla Minecraft's other data files.

    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 11 latest files checked, last on 20 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.
      11 latest files: the newest file for each Minecraft version and loader. The answer above is about the 9 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, 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 9 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 9 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

    An AI tool may have been used

    Claude Code is named in the ignore list of its repository.

    This does not show that it was used to make the files you download.

    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 · 6 places read
