AuraUtility
by Zayb
AuraUtility shows Oxygen timers, Mending notifications, low-health warnings and an item counter on the Fabric client, without changing the server.
What it does
When a player is underwater, a precise digital timer on the HUD counts down the seconds of air left before drowning. A separate notification appears whenever an item is repaired with Mending, naming the item so the player can see exactly which tool was fixed, and the position of that notice on screen can be chosen.
Danger Borders draw a subtle red vignette that flashes when health falls below three hearts, a warning meant for intense combat. An item counter reports the total amount of a chosen item across the whole inventory and hotbar. The mod is client-side only, so servers run without it. It requires Fabric API on Fabric for 1.21.3, and files also cover 1.21, 1.21.1 and 1.21.2 under the MIT License, which is not open source.
Pressing the K key opens the settings menu, where each feature can be switched off and the HUD colors change at once. Some changes do need a game restart. The build is small and aims to keep the HUD uncluttered for survival, PvP and technical play.

Use cases
Who it’s for: Players who want small, client-side quality-of-life information on the HUD. Only the client needs the mod, so a server can host it for players who install it.
How it compares
Low Health Warning is Fabric and client-side only, released under the MIT License, and covers 1.21.1 – 1.21.11. Totem Assist is also Fabric and client-side only, but it is published under All rights reserved for 1.21.4 – 1.21.11, so it does not cover AuraUtility's 1.21 – 1.21.3 files. XP Repair HUD targets only 1.21.11 and is released under the MIT License.
