WHO IS THIS – Anti Invisibility
by Gugopleks
Players under an invisibility potion who put on a piece of armor become visible to others, which Who Is This sets up on Fabric.
What it does
Who Is This makes a player who is under the effects of an invisibility potion show up again once any piece of armor is equipped. Without armor the potion works as usual, so invisible players stay hidden from others who do not wear armor, and the mod is meant for situations where hiding would otherwise be treated as cheating. The author notes that server administrators should be asked before the mod is used on a server.
The mod is a Fabric build for 1.21.11 only, released 2026-04-08 and last updated the same day. It runs on the client alone, so players install it and servers do not need it. It is distributed under All rights reserved, so the code is not open source.
