Health Display Datapack
by LoEoD
Health Display Datapack shows each mob's health as a percentage above its head, updating as the mob takes damage, using a data pack rather than a mod jar.
What it does
The datapack gives real-time health percentage displays for mobs. The percentage appears above a mob and changes as its health changes, and the information is shown only when a player is close to the mob, so distant mobs stay unlabeled.
The display is built on the mob's custom name, which means it can conflict with other sources of custom names. Uninstalling the datapack removes the labels, and any mob that already had a custom name before installation loses that name once the datapack is removed. Players who want a more polished look can add a resource pack that restyles the percentage text.
Installation needs only a data pack, and the mod is published for Fabric, Forge, NeoForge and Quilt, plus data pack use on server platforms. The server must run the datapack, while players may leave it out. Game versions 1.21.5 – 1.21.6 are covered, with 1+mod for 1.21.6 as the latest file, first published and last updated on 2025-06-29. The mod is released under All rights reserved and is not open source.
Key features
Real-time health percentage
Mobs display their current health as a percentage that updates immediately after every change in health.
Proximity-based labels
The percentage is shown only for mobs near a player, which keeps distant mobs from cluttering the screen.
Resource pack styling
A resource pack can change how the percentage text looks, for players who want a different visual style.
Tag-based setup
The function uses entity tags to select which mobs receive a health display.

How it compares
Health Display Datapack runs as a data pack, while Health & Damage HUD is a mod for Fabric, Forge, NeoForge and Quilt, covering 1.21 – 1.21.1 and also requiring the server to run it. How Much Health is a Fabric mod for 1.21 that is client-side only and open source under the Apache License 2.0, so it changes nothing on the server.
