Inspector 🔎
by fnn
Inspector lets players right-click a block with a magnifying glass and see its full recorded history, including who changed it and when.
What it does
The Inspector mod logs block breaks and placements, fluid changes, container transactions, entity kills, redstone interactions, anvil use and player-caused explosions into a SQLite database, with each entry attributed to a player and timestamped. The history screen that opens lists each logged entry for the block under inspection, marking every row with a player head, an item icon, a color-coded action and a relative timestamp. Hovering an entry shows a tooltip with more detail.
The magnifying glass is a craftable tool with 256 durability, so inspection stays a survival-friendly action rather than a command. The mod is published for Fabric and NeoForge across six release versions, 1.21.1 – 26.3, and it runs on client and server, so both the server and every player need it. Its required dependency is YetAnotherConfigLib (YACL), and Mod Menu is optional. The code is not open source, and the mod is released under All rights reserved.

How it compares
NeoProtect is a server-side only protection mod, published under All rights reserved for 1.21.1 – 1.21.11 on Fabric, Forge and NeoForge, and it is not open source. Inspector covers history inspection rather than protection, and it needs a client install as well as the server. MineTracer is server-side only, open source under the MIT License and built for Fabric across 1.20.1 – 26.3, so it offers a different logging scope on Fabric alone.
