ZConfig

by Reverie Projects

Players and server owners who want a config library for Fabric and Quilt mods can use ZConfig, a mixin config plugin that reads TOML files.

FabricQuiltClient or server, optionalMozilla Public License 2.0Open source1.21 – 26.3

What it does

ZConfig reads TOML config files and exposes boolean and integer entries to other mods. Mod authors can generate a config from a short declaration, so less boilerplate is needed in each mod. The library also lets other mods override a config entry through mod metadata, which lets a pack author adjust a value without editing the original file.

A mod can be marked as incompatible with specific config entries, so the game warns when a conflicting setting is turned on. The library is published for Fabric and Quilt, with files for 26.3 covering game versions 1.21 – 26.3. It works on either side, and neither needs it. The code is released under the Mozilla Public License 2.0, and the project is open source with public source code and an issue tracker. Snapshot builds are published as well.

Key features

  1. TOML config files

    Configuration is stored in TOML files, a plain text format that can be read and edited by hand.

  2. Boolean and integer entries

    Config entries can be booleans or integers, covering switches and numeric limits in other mods.

  3. Metadata overrides

    Other mods can override config entries through their mod metadata, without changing the original config file.

  4. Incompatibility markers

    A mod can be marked as incompatible with certain config entries, so conflicting options are flagged.

  5. Generated config sugar

    Helper syntax generates config classes with less code, reducing the setup work for each new mod.

Use cases

Config for library mods

Mod authors who build several Fabric or Quilt mods can use one shared way to declare and read their settings.

Pack-level tuning

Modpack authors can override entries from another mod's metadata, adjusting behavior without patching its files.

Who it’s for: Mod developers building Fabric or Quilt mods who want generated TOML configs, and modpack authors who tune several mods from one place.

How it compares

Full comparison

OmniMixin runs on Fabric only, for 1.21 – 1.21.1, and is not open source, so it is not a config library and does not match ZConfig's range. Tag Exclusion is server-side only, open source under the MIT License and covers 1.21 – 26.1.2, so players can join without installing it. Interference API is open source under the MIT License, works on client and server and covers 1.17 – 1.21 on Fabric.

Questions

Does ZConfig need to be installed on the server?

No. It works on either side, and neither needs it, so installing it on one side is enough.

Fabric and Quilt. The latest files for both loaders are 1.0.0+26.x for 26.3, published on 2026-08-03.

Which mods depend on ZConfig?

Three catalog mods require it, for example Fast Noise, Fast Surface and Material Rule Compiler.

In the catalog

ZConfig is one of 3,514 Library mods on ModsFinder, and one of 2,348 Library mods for Fabric. 8,071 mods support Minecraft 26.3.
