Private Vault
by FourTerms2
Private Vault gives each player a personal storage inventory on a Fabric server, with a size limit that the server owner sets.
What it does
Players open their own vaults, and the number they can hold is capped by a configured limit that can reach 100,000 items. Vaults are stored by UUID, so offline players keep their contents and admins can still reach them. Vault data is kept in the world folder inside world/data/private vaults.dat and loaded at startup, so vaults persist after a server restart. Both the save file and the vault settings are managed automatically, with no need to edit files by hand.
The mod is server-side only, so players join without installing it, though clients that do install it are noted in the author text. It also works in singleplayer, where the same vault system is available to the one player. Files are published for Fabric only, for six game versions 1.21.11 – 26.3 (the "1.21.11 – 26.3" range), and Fabric API is required beside it. The code is MIT licensed but the project is not open source.
Key features
Personal vault storage
Each player gets a vault that stores items separately from their inventory and from other players.
Configurable item limit
A server-side limit sets how many items each player's vault can hold, and it can be raised or lowered at any time.
Limit reductions keep items
When a limit drops, items above the new cap stay in the vault and cannot be opened until the limit is raised again.
Admin access by UUID
Vaults are tied to player UUIDs, so an admin can open a vault of a player who is offline, with the online player targeted through a configuration command.

How it compares
Auto Vault is client-side only, MIT licensed and open source, published for Fabric on 1.21.4 – 26.1.2, so it differs from Private Vault in where it runs. Virtual Storage is also server-side only and open source under the MIT License, but its files cover 1.21.8 – 26.1.2. Dawn Vaults is server-side only and loads on Fabric and NeoForge for 1.21.1, with All rights reserved rather than an open license.
