Player Outlines draws a colored outline around other players so they stay visible through walls, on Fabric for 1.21 – 26.2.

What it does

The outline sits on each player's hitbox and is drawn in red, and its reach can be adjusted so only players within a chosen distance are highlighted. The option to turn it off entirely, or to bind it to a key, lives in the mod's settings. Because the highlight shows through walls, some servers count it as cheating, and players should check a server's rules before using it there.

Only the client needs the mod, and Fabric API is required beside it. Player Outlines is released under the MIT License and is not open source, with files for 1.21 – 26.2 on Fabric.

Key features

Red player hitboxes
Other players are outlined in red along their hitbox, so they can be spotted at a distance.
Adjustable highlight range
The distance at which players are highlighted can be changed, limiting the outline to nearby players.
Toggle on demand
The outline can be disabled entirely or switched on and off with a key, so it is not always active.
