Item Editor

A client-side in-game item component editor for Fabric.

Item Editor opens a full editor UI for the item currently held by the player and lets you work on a safe draft before applying changes. It uses modern item component editing instead of old raw-NBT-only workflows and supports dynamic editors for many special item types, including books, banners, fireworks, containers, signs, potions, and more.
