XP: DevTools
by HER0XP
XP: DevTools is a Forge and NeoForge utility with a hammer for spawning loot-table chests, a copy tool for entity IDs and NBT data, and quick game mode switch buttons.
What it does
Holding the hammer and clicking a loot table entry in the tool window sets that table, then a right-click spawns a chest holding its loot, facing the player. Shift with the tool opens the selection window. Right-clicking an entity copies its ID to the clipboard, such as minecraft:zombie, and Shift with a right-click copies the complete NBT data. Quick game mode switch buttons sit on the pause screen at the top of the inventory, so players can change modes faster.
The tools target datapack creation, debugging and inspecting entity properties without commands. The mod is meant for modpack makers and server owners who want a shared style, and it works alongside the vanilla game. It runs on client and server, so both sides need it. Builds cover 1.20.1 and 1.21.1 for Forge and NeoForge, with Forge 1.0.7 for 1.20.1 and NeoForge 1.0.5 for 1.21.1 as the latest files. All rights reserved; the code is not open source.
Key features
Loot table chest spawner

Developer-focused tools
The toolset supports datapack work and entity inspection without commands, and the author plans to add more tools.

How it compares
NBT Copy is open source under the GNU Lesser General Public License v3.0 only, supports Fabric, Forge and NeoForge, and can be installed on either the client or the server. CHCP is client-side only, runs on Fabric and Forge for 1.20.1 – 1.21.11, and is not open source. QuickCopy is client-side only for Forge 1.20.1 under the MIT License. XP: DevTools needs both the client and the server, so its environment differs from all three.
