Alert
by b1nt1n
Alert warns a player on the HUD when health drops, gear is close to breaking, or a potion effect is about to expire.
What it does
Alert is a Fabric mod that shows warnings on the HUD in three cases: health falling below a chosen threshold, armor, offhand or hotbar items nearing the end of their durability, and potion effects running out. Each warning can appear as a visual pop-up or a toast, and can play a sound, so a player learns about a problem without watching the status bar. The timing and placement of the alerts are set by the player.
The mod runs on the client only. Servers do not need it, and players join a server without installing anything. It is published for Fabric and targets 1.21.4 and 1.21.11, with 1.0.1 for 1.21.11 as the latest file, released on 2026-07-03 under the MIT License. Alert is not open source.
Key features
Low health alerts
A warning fires when health drops below a threshold the player sets, with a visual and audio signal.
Durability warnings
Armor, offhand and hotbar items are scanned, including the inventory, and warned about before they break.
Potion effect timers
An alert appears shortly before a buff such as Fire Resistance ends, with the warning time adjustable.
Alert sound choice
Players can pick the vanilla pling or load their own .wav file as the alert sound.
Customizable HUD
Pop-ups and toasts can be moved, scaled and set to a duration, anywhere on the screen.

Use cases
Long nether trips
A timer warns before Fire Resistance runs out, so the player can drink another potion before returning to the Nether.
Combat with thin armor
Durability alerts flag a piece of armor or a weapon before it breaks mid-fight.
Who it’s for: Players who want timely warnings on their own screen. Because it is client-only, it suits single-player worlds and multiplayer servers alike.
How it compares
Alert is client-only, like Low Durability Warning, which is open source under the MIT License and targets 1.21.11 alone. Breaking Warning runs on both client and server, is not open source and targets 1.21.11. Potion Notifier also needs both sides, is licensed under the Apache License 2.0 and targets 1.21.11. neverfake's Low Health Warning is client-only, covers 1.20.1 – 1.21.5 and is not open source.
