Durability Alerts

Durability Alerts is a Fabric mod that watches six equipment slots: the main hand, the offhand and four armor pieces. When an item crosses one of its configurable thresholds, the mod shows a warning with its own message and sound. A compact heads-up display in a corner lists the items running low, worst first, with a bar that shifts from green to amber to red as the item wears down. Only items below the highest threshold appear there, so a freshly crafted wooden shovel stays out of view until it is half worn.

The mod ships with three alerts, and a menu lets the player change them, set exact hit counts, and pick a Minecraft sound from a list with instant preview. A large on-screen alert can be sized, placed and timed, with an optional dark backdrop. The corner display can sit in any of four corners or be turned off. A test alert button in the settings shows how each alert looks without breaking a tool. The mod can also switch to a healthier tool before the current one snaps.

Durability Alerts is a client-side only mod: it runs entirely on the client, works on a server running vanilla, and needs nothing installed on the server side. Builds are published for Fabric only, for the game versions 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11 and 26.1, with 1.5.3 for 1.21.11 as the latest file. Builds for 1.21.9 and later are separate because the key binding API changed in that release. The code is under the MIT License, and the project is not open source.
