Minecraft (NeoForge) - free & open source
A modern NeoForge rewrite of the classic MobHealth Bukkit plugin. Hit a mob and MobHealth tells you exactly what you did to it and how much health it has left - through any combination of seven display modes, from vanilla-friendly text to real floating bars.

Display modes
All seven modes can be enabled independently. The first four are server-side and work on completely unmodified vanilla clients - players don't need to install anything. Toasts, graphical bars and damage indicators are client-rendered and need the mod on the client too.
Damage dealt and health remaining, sent to your chat log.
The same readout on the text line just above your hotbar.
A coloured health bar on the mob's name tag above its head.
The vanilla boss-bar widget at the top of your screen.
An achievement-style popup with a heart, the mob's name and the weapon used.
A crisp pixel health bar floating above the mob in the world.
Red numbers that pop off the mob for each hit, rise and fade over about a second. The killing blow is drawn bold, larger and amber. The one mode that reports the hit rather than the mob's state, so it needs MobHealth on both sides - a client can see health drop, but a drop is not the same thing as a hit.
Bars are coloured by remaining health: green → yellow → red.
Targeting
Appearance
Install however suits your server
Install on a dedicated server and every player gets chat, action bar, nameplate and boss-bar readouts without downloading anything - vanilla or modded. Players who also install MobHealth additionally get toasts, graphical bars and damage indicators. Client-only on a vanilla server still gets you graphical bars over anything you can see.
Damage indicators are the one mode that needs both sides: the number only ever exists on the server, because a drop in health is not the same thing as a hit - absorption, regeneration and healing all move it too.
Dig deeper
Two TOML files, generated on first run and editable in-game via
Esc → Mods → MobHealth → Config:
mobhealth-common.toml for what is shown, to whom and how, and
mobhealth-client.toml for the look of your own graphical bars. Plus ready-made recipes for common setups.
/mobhealth toggle mutes or unmutes your own displays, and persists across logouts.
/mobhealth reload re-pushes settings to online players - rarely needed, since config edits apply on save.
Requirements
MobHealth ReForged ships for three Minecraft versions. Download the file for yours - the Minecraft version is in the filename, so there is no guessing which is which.
| Minecraft | NeoForge | Java | File |
|---|---|---|---|
| 1.21.11 | 21.11.42+ | 21 | mobhealth-2.5.0+mc1.21.11.jar |
| 26.1.2 | 26.1.2.95+ | 25 | mobhealth-2.5.0+mc26.1.2.jar |
| 26.2 | 26.2.0.59+ | 25 | mobhealth-2.5.0+mc26.2.jar |
The Java version tracks Minecraft, not MobHealth - 26.1 ships its own Java 25 runtime to players, so the launcher handles it for you. No other dependencies.
