NBT Viewer (Fabric)

Minecraft players who love technical gameplay, map making, or advanced redstone know that NBT data is the hidden language of the game. Every item stack carries a wealth of information—enchantments, custom tags, durability, and even modded data—that the vanilla interface never shows. NBT Viewer (Fabric) changes that by bringing a clean, client-side GUI straight into your game, letting you see exactly what is attached to the item in your hand.

This mod is built specifically for the Fabric mod loader, which means it is lightweight, fast, and integrates smoothly with modern Minecraft versions. Whether you are debugging a custom datapack, checking the integrity of a modded item, or simply satisfying your curiosity about how the game stores data, NBT Viewer (Fabric) delivers the answers with a single key press.

What Does NBT Viewer (Fabric) Do?

At its core, the mod adds a key bind—defaulted to Right ALT—that opens a GUI showing the full NBT data associated with the item stack currently held in your hand. Instead of using cryptic commands or external tools, you get an in-game window that presents the data in a structured, expandable tree format.

Key Features

Full NBT display: Every tag, from simple integers to complex compound lists, is shown in a readable GUI.
Arbitrary nesting support: Large and deeply nested NBT objects are handled gracefully, so you can expand and collapse nodes as needed.
Lightweight and compatible: Works with vanilla items, modded items, and any custom NBT data added by other mods.
Fully client-side: No server-side installation is required, making it safe for use on multiplayer servers that do not allow gameplay-affecting mods.

The GUI itself is constructed using LibGUI, a library that ensures a consistent and responsive interface. This means the mod does not interfere with your normal gameplay—it simply sits in the background until you press the key bind.

Supported Versions and Loader

NBT Viewer (Fabric) is designed exclusively for the Fabric mod loader and requires Fabric API and Kambrik as dependencies. The mod is available for a range of recent Minecraft versions, so you can easily find a build that matches your game. Always check the mod page for the specific version compatibility before downloading, as Fabric versions are updated regularly.

Because the mod is client-side, you can use it on any server, even those that do not have the mod installed. This makes it an excellent tool for players who want to inspect item data without affecting server performance or requiring administrator approval.

How to Install NBT Viewer (Fabric) for Minecraft

Installing the mod is straightforward if you follow these steps. Before you begin, ensure you have the correct version of Minecraft and Fabric Loader installed.

Step-by-Step Installation

Planned Features and Future Development

The developer has outlined several exciting additions for future releases. Among the most anticipated are the ability to access Block Entity and Entity data directly from the GUI. This would allow players to inspect the NBT of chests, signs, mobs, and other world objects without needing to use external editors or complex commands.
