A shared library required by all YUNG's Better mods, providing structure generation utilities and jigsaw helpers.
Overview
YUNG's API is a library mod created by YUNG. A shared library required by all YUNG's Better mods, providing structure generation utilities and jigsaw helpers. As a library mod it concentrates on shared code that other mods build on, and it has been downloaded around 55 million times, which puts it among the options players reach for in this space.
YUNG's API is built for players installing any of YUNG's structure mods, which require it. It is the shared library powering YUNG's Better Dungeons, Strongholds, Mineshafts, and more, so it is installed as their dependency. It is approachable enough to drop into a world and use right away, with little setup required.
The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

How to install YUNG's API
YUNG's API supports Forge, Fabric, and NeoForge; pick one loader (you cannot mix them) and install it for your chosen Minecraft version. It is built for Minecraft 1.20.1 and 1.21.1, so make sure your profile uses one of those versions.
- 1Choose and install one mod loader from Forge, Fabric, and NeoForge for a Minecraft version this mod supports (1.20.1 and 1.21.1).
- 2Check the download page for any required libraries. YUNG's API lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the YUNG's API .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and make sure every connecting player has it too.
- 4Launch the game with that loader profile and confirm YUNG's API appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
Supported Minecraft versions: 1.20.1 and 1.21.1. Always download the build that matches your version exactly, as mod files are version-specific.

Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.
As a library mod, YUNG's API adds no content of its own and has a negligible footprint, it exists to support the mods that depend on it.
If you are comparing options, a similar mod worth a look is (no direct alternative, it is a dependency library). They overlap in purpose, so most players pick whichever suits their loader and pack.
