Rent Server with this Mod

About this Mod

All players share the exact same inventory. Changes made by one player instantly affect everyone's inventory.

This also includes your hunger bar — it is shared as well.

When "keepInventory" is turned off, if Player A dies and drops all their items, the inventories of all other players (B, C, D) will also be emptied — because you're all sharing the same backpack. haha

Frequently Asked Questions

One Inventory server crashes on startup – what to do?

Is One Inventory compatible with forge and neoforge?

One Inventory officially supports forge, neoforge for Minecraft 1.20.6, 1.20.5, 1.20.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with One Inventory – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if One Inventory 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.
