Leave Confirm
Leave Confirm opens a confirmation popup before a player disconnects from a multiplayer server, which helps prevent accidental combat logging.
What it does
Leaving a multiplayer server normally happens with one click, so a stray press can disconnect a player in the middle of a fight. Leave Confirm places a confirmation popup in front of that action, and the player must accept it before the connection closes. The popup shows the player's head, which ties the prompt to the character being played.
The mod runs on the client only, so only the player who installs it sees the prompt. Servers do not need to install anything, and vanilla servers work without changes. Mod Menu support lets players open the settings screen from the mod list, where a color picker changes the color of the popup. Language support covers English and German.
Installation needs Fabric API alongside Fabric Loader. The mod is released under the MIT License, and its source code and issue tracker are public. The latest build, 1.1.3, was published on 2026-06-28 for Minecraft 1.21.11 only.

Use cases
Protecting fights on multiplayer servers
A player in a combat situation can stop an accidental disconnect, since the leave action waits for a second confirmation.
Who it’s for: Players who join multiplayer servers on Fabric and want a guard against disconnecting by mistake. Only the client needs the mod, so server owners do not have to add anything.
