This is a simple mod for the Fabric Loader, that renders a simplistic bar made of pipe symbols (|), that represents the health of the Entity you are looking at.
This image is simply the mod's in-game Icon, and site Banner.
This screenshot shows how the mod would show the health of an entity when its health is full.
This screenshot shows how the mod displayed the health of a Husk, when its health was low, compared to when at full HP (2nd screenshot in Gallery).
This screenshot shows how the bar & text would look like, as a close-up view.
