VoidQuit

Automatically quits the world the moment you fall below the void threshold — never lose your items to the void again.

Features

Checks your Y coordinate every tick and exits the world before void death
Works in all game modes: Survival, Creative, Adventure, Spectator (Hardcore worlds use the Survival rules)
Singleplayer: saves and returns to the title screen; Servers: disconnects back to the server list
Trigger depth, cooldown, and exit message are all configurable
Built purely on Fabric API events — no mixins, maximum compatibility
