InvHistory

by Calamech

InvHistory is a server-side mod that records player inventories over time so administrators can look back at them and roll back losses.

What it does

InvHistory tracks changes to each player's inventory and stores periodic records of them. Records are taken on a configurable interval and on events such as joining, leaving and dying. An MD5 hash check means a record is only kept when the inventory has actually changed. Storage uses compressed NBT to keep the saved history small.

Administrators open a player's history in a chest-style interface, browse entries by timestamp and event reason, and restore a chosen entry with a two-click confirmation. The mod was designed for anti-cheat rollback and for investigating inventory losses caused by bugs or exploits. It is licensed under the Apache License 2.0 and is not open source.

Players need nothing installed, since the mod runs only on the server. Files are published for Fabric and NeoForge, with the latest build, 1.0.0, targeting 1.21.11 and dated 2026-02-23. Builds cover 1.21 – 1.21.11 across 11 release versions.

Key features

  1. Automatic recording

    Inventories are saved on a set interval and when players join, leave or die, without manual action.

  2. Change detection

    An MD5 hash comparison keeps a record only when the inventory differs from the previous one.

  3. Chest-style history browser

    Administrators page through a player's history in a chest-style screen with timestamps and event reasons.

  4. Two-click restore

    An entry can be restored from the interface, and a second click confirms it to prevent accidents.

  5. YAML configuration

    Interval, maximum stored entries per player, tracked events and permissions are set in a YAML file.

Use cases

Who it’s for: Server owners and moderators who need a record of player inventories and a way to restore them. Players on a server that runs the mod do not install anything.

Questions

Does InvHistory need to be installed on player clients?

No. Players join without it, since only the server has to run the mod.

Which loaders does InvHistory support?

Fabric and NeoForge. Files for both are published at version 1.0.0 for 1.21.11.

Does InvHistory store every change to an inventory?

No. A record is kept only when the inventory's MD5 hash differs from the previous one, and records are also taken on the configured interval and events.
