KastNPC
by kast1ent
Players who want placeable characters for scenes, maps or roleplay can use KastNPC, a Fabric mod that adds customizable NPCs to the world.
What it does
KastNPC lets a creator place a character directly in the world and change how it looks: a player model, a mob model, a skin, armor, held items and a name. Each NPC can be posed and its pose adjusted, which suits staged scenes and map work. The mod is aimed at content creators, map makers and roleplay projects, and the author describes it as KastNPC's own alternative to NewNPC.
The mod runs on Fabric for Minecraft 1.21.4 only, and the files are published with 1.0.7 as the latest build, dated 2026-05-24. Servers that run it need every player to install it too. The license is All rights reserved, which means the code is not open source. The author links an issue tracker for bug reports.
Key features
Placeable NPCs
NPCs are placed in the world as standing characters that stay where the creator puts them.
Player and mob models
An NPC can take the form of a player model or one of many mob models, from common animals to hostile mobs and bosses.
Skins and 3D skin layers
Skins can be applied to an NPC, and the mod draws 3D skin layers on the model.
Poses and animations
Each NPC can be posed and given animations, so characters can be arranged into scenes.
Equipment and held items
Armor and held items can be set on an NPC, along with a custom name shown above it.

How it compares
Emotecraft x Easy NPC is a Fabric mod for 1.21.1 – 1.21.11 that is client required, with the server optional, and it is not open source. Customize Your Skin is client-side only and covers 1.21 – 1.21.4, but it changes the skin of the player rather than placing NPCs. KantoNPCs is also a client and server Fabric mod, limited to 1.21.1 and under a custom license.
