This Datapack/Mod links your Inventory with all other players, making for an interesting playtrough with your friends!
About this Mod
With this datapack/mod installed, you and your friends all share one Inventory!
This applies to your Hotbar, Inventory, offhand and your armor slots.
This project is both available as a mod and a datapack. If you install the mod you'll still need to enable the datapack from the world creation screen.
INSTALLING THIS AFTERWARDS WILL DELETE THE INVENTORY OF EVERY PLAYER EXCEPT ONE. THIS IS IRREVERSIBLE
The Commands used where shown in this video by BlockerLocker. I just made them into a datapack!

Inventory Link server crashes on startup – what to do?
Most common cause: wrong datapack version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is Inventory Link compatible with datapack and fabric and forge and neoforge and quilt?
Inventory Link officially supports datapack, fabric, forge, neoforge, quilt for Minecraft 1.21.11. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Inventory Link – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Inventory Link consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
