About this Mod
📌 NearbyAlert
NearbyAlert is a lightweight client-side Fabric mod that warns you when other players are close.
When a player enters a 150-block radius, a clean on-screen alert appears showing their name and the direction they’re coming from. If multiple players are nearby, NearbyAlert intelligently cycles through them so your screen stays uncluttered.
