Observer
Observer is a Fabric social mod that has fake player figures appear behind players in the world, placed at random out of sight.
What it does
Observer periodically picks a random online player and places an observer figure at a configurable distance behind them, in a dark, isolated spot. Each observer wears a custom skin that can be set in the configuration, and it turns its face toward nearby viewers individually, so each player sees it react to them alone. The figures are invulnerable, hostile mobs ignore them, and they are hidden from the tab and team lists. After a short interval they despawn on their own.
Timing, distance and the appearance of the figures can be adjusted through Cloth Config. Mod Menu adds an in-game configuration screen for the same options, and that screen is optional. The mod runs on client and server, so the server and every player need it, and the license is GNU General Public License v3.0 only, with the source code published.
Installation needs Cloth Config API, Fabric API and Fabric Language Kotlin. Files are published for Fabric for 26.1.2, first released on 2026-08-10 as version 0.1.0.
