Return by Death

Return by Death is a Fabric rollback mod. When a player with Return by Death enabled would die, death is cancelled and the world is restored to that player’s latest timeline checkpoint.

The mod tracks player state, blocks, block entities, items, mobs, entities, scheduled ticks, weather, time, and related world state to make the rollback feel close to a real rewind.

Notes

Safe checkpoints may delay automatic checkpoint creation while the checkpoint owner is airborne, in lava, in water or swimming, on fire, recently damaged, in active combat, near hostile threats, using an open container, or carrying a cursor item.

/rbd checkpoint force bypasses safety checks. /rbd rewind manually restores the latest checkpoint without needing to die.

Scope

Return by Death supports singleplayer, Open LAN, and dedicated multiplayer servers. Multiplayer support is designed for small groups and uses a shared world timeline with per-player checkpoint ownership.
