Imposter Mod
by StormLineMC
Imposter Mod brings a social deduction round to a Fabric server, where a few players secretly work against the rest and the others must find them.
What it does
Each round, the server picks imposters at random from the connected players, along with detectives and other roles set in the configuration. Players who are not imposters have to work out who is lying from what they see and hear during play. A detective gets one guess per round that can expose an imposter, while an accusation against an innocent player removes the accuser and the accused from the round.
The mod ends a round automatically once a winning side is reached, using win conditions that the server owner can adjust. A countdown runs at the start of each round, and players who die continue as spectators until the round ends. Several imposters can be active in the same game. The mod requires Fabric API on Fabric and is published for 1.21.4 only, with the Fabric build 1.0.0 dated 2026-06-21. Only the server has to run it, and players may leave it out. It is released under the MIT License and is not open source.
Key features
Random imposter assignment
Imposters are chosen at random at the start of each round, so no two rounds play out the same way.
Multiple imposters
More than one imposter can be active in a single game, which changes how the group reads each player.
Customizable roles
The roles in a game can be adjusted, letting the server owner decide which parts take part.
Detective guess
The detective has one guess per round that can identify an imposter, and a correct guess ends the round in that side's favor.
Automatic round win detection
The server checks the win conditions during play and ends the round when one of them is met, with no manual step.

How it compares
DeadTell is a Fabric mod for 1.21.1 that is client and server and under All rights reserved, so it differs from Imposter Mod in version and license. X Wathe Roles is also Fabric, for 1.21.1, client and server, under All rights reserved, and is not open source. SenseSwap covers 1.21 – 1.21.4 under the MIT License, which overlaps with Imposter Mod's version and license but runs on both client and server.

If they accuse an innocent…
