Shared Inventory – Fabric 1.21.x

Shared Inventory is a Fabric mod that makes players share their inventory with each other.

If one player picks up an item, crafts something, mines blocks, drops items, or uses resources, the inventory updates for everyone in the same team. This makes survival feel more cooperative and forces players to actually work together instead of playing separately.

The mod also supports multiple inventory teams. This means you can split players into different groups, and each group will have its own shared inventory. It works well for team challenges, LAN worlds, survival experiments, or team-vs-team gameplay.

There is also an optional shared hearts system. When it is enabled, players in the same team share health behavior. If one player takes damage, the team feels it too. Knockback is also synchronized, so damage affects the team more naturally.

Main features:

Shared inventory between players
Separate shared inventories for different teams
Optional shared hearts
Knockback sync when shared hearts are enabled

Designed to avoid inventory resets and item duplication after death or respawn
