    About

    BCLib is a developer library for BetterX mods such as BetterEnd, BetterNether, and Eden Ring, and also provides reusable tools for creating other mods. Its world-generation compatibility lets biomes from different Nether and End mods or datapacks generate together, using the BetterX world type, which also offers specialized settings. For mod authors, it includes APIs and templates for building blocks, biomes, features, and structures; registering tags and recipes; managing world-specific data; and defining custom world types and surface rules. Additional development tools cover procedural block and item models, rendering interfaces, plant growth, biome data and fog, noise and math utilities, splines, and signed-distance-function operations for block processing and feature generation. BCLib also provides configurable, automatically generated block and item models, reusable content-generation helpers, and hierarchical JSON configuration with client-server synchronization. For players, it supplies emissive textures for supported blocks, including resource-pack support, and a screen that notifies users when BetterX mod updates are available.

    Security

    No harmful code found

    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. Only in its files for Fabric 1.20 to 1.21.1. See Privacy
    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 1.20.1.

    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 15 latest files checked, last on 18 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.
      15 latest files: the newest file for each Minecraft version and loader. The answer above is about the 6 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.
      Other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends about you

    We read its code without running it: it contacts 1 web address while you play.

    Like any connection, each address it contacts sees your IP address.

    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.
      The code of all 6 files, for recent Minecraft versions. See each file in Releases
    • wunderreich.ambertation.de
      Checks for a new version of the mod.
    • 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 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 · 6 places read
    • Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.

    Known conflicts

    These projects do not work together with BCLib: their authors or BCLib's author say so. If you install both, the game can crash or some features can stop working. Some of them do the same job as BCLib, so you only need one.
