Do I need FTB Library if I'm using other FTB mods?

Yes. FTB Library is a dependency for other FTB mods like FTB Chunks, FTB Quests, and more. Without it, those mods won't load. You need to install it for any FTB mod to work.

Is FTB Library compatible with non-FTB mods?

FTB Library works with any other mod as long as they're all running on the same mod loader. It won't cause conflicts with other mods you have installed.

What's the difference between the Forge and Fabric versions?

They're the same mod, just compiled for different mod loaders. Use the Forge version if you're using Forge, and the Fabric version if you're using Fabric. You only need one.

Do I also need Architectury API?

Yes. Architectury API is a separate requirement for FTB Library to work properly. Download and install it along with FTB Library.

Which Minecraft version should I download?

Download the version that matches your Minecraft installation. For example, if you're playing on 1.19.2, download the 1.19.2 version. The mod loader (Forge or Fabric) must match what you're using too.

FTB Library Mod 1.19.2, 1.18.2 Download

FTB Library is a library mod used by pretty much every FTB mod. It handles GUI creation, SNBT tools, and other utility stuff that FTB’s other mods depend on. If you’re running mods like FTB Chunks or FTB Quests, you need this installed.

Features

GUI System

FTB Library includes a component and layer-based GUI creation system. This is what lets FTB’s other mods build their interfaces. Think of it as the backend that makes all those fancy GUIs possible.

SNBT Tools

Includes useful tools for working with Minecraft’s text format, including SNBT parsing and generation. Handy if you’re messing with config files or custom content.

Core Utilities

A bunch of handy tools and functions that FTB mods use under the hood. You don’t interact with it directly, but it makes everything else work smoothly.

Requirements

FTB Library needs one of these mod loaders:

You’ll also need Architectury API.
