Who's There is a lightweight HUD mod for Minecraft Forge that helps you stay aware of nearby hostile mobs without filling your screen with heavy UI.
When danger gets close, a subtle >-shaped directional indicator appears near the edge of your screen and points toward the threat. The indicator changes color based on distance, shifting from a warning tone at range to a more urgent color when enemies get dangerously close.
The mod is designed to stay simple and readable while still fitting naturally into gameplay. It also includes an in-game config menu, so you can adjust things like detection range, maximum indicators, and the shape settings of the directional marker to match your own preference.
If you want a cleaner way to notice threats around you without constantly spinning your camera, Who's There is made for exactly that.
