Private-chest
Private-chest lets a player lock a chest so that other players cannot open it, which suits shared servers where storage should stay with its owner.
What it does
A chest placed by a player can be locked to that player, so other visitors are kept out of its contents. The lock covers the chest itself and works on the server, so it applies to every player who joins without installing anything extra. Players who want a fully closed storage area should lock both halves of a double chest, because each half is a separate chest and a single locked half leaves the other half open.
The mod is server-side only: the server runs it and players need nothing installed. It requires Fabric API on the Fabric loader and is published for Minecraft 1.21.4 only. The author marks a known issue in the current build, so server owners should test locking and access before relying on it for protected storage.
Private-chest is released under the MIT License and is not open source in the sense of publishing its full project under an open license of the same kind as the copyleft options. Its first and latest file are both dated 2025-07-17 and are marked as a beta build.
Key features
Locked chests
A chest can be locked so that only its owner opens it, keeping storage away from unwanted visitors.
Double chest handling
Each half of a double chest needs its own lock, so both halves must be locked to protect the whole chest.
Server-side operation
The lock runs on the server alone, so players join without installing the mod.
Known issue flagged
The author lists a known issue in the current build, so the mod is at an early beta stage.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Server owners running Minecraft 1.21.4 with Fabric who want players to lock their own chests. Because the mod is in beta, owners who need dependable protection should test it on a copy of their world first.
How it compares
Craft From Chests and Smart Chests both need the client and server, and neither is open source; Craft From Chests covers 1.21.1 – 1.21.11, while Smart Chests is limited to 1.21.11. Bigger Ender Chest is server-side only and MIT licensed, but is not open source. Lock & Order also needs the client and server and is not open source, with builds for 1.20.1 – 1.21.1.
