AquaGuard
by denfry
AquaGuard is a server-side audit logging mod that records block changes, container activity and player actions into a database for later inspection and rollback.
What it does
On modded Fabric, Forge and NeoForge servers, AquaGuard records server-side events, covering block breaks and placements, container and sign edits, entity interactions, deaths, logins, logouts, explosions, and natural changes like fire, leaf decay and falling blocks. Moderators can switch into an inspect mode, click a block and see its recent history with timestamps and stored details. Rollbacks can be previewed for an area, reversed or re-applied, and run in small batches each server tick to avoid lag spikes.
Storage uses SQLite out of the box, or MySQL and MariaDB when several servers should share one database. Writes pass through a bounded queue handled by a dedicated database thread, and lookups run on separate worker threads. Companion mods can report their own attributed actions via AquaGuardAPI, which places those records alongside vanilla events in one history. Installation requires Fabric API. AquaGuard is server required, with the client optional, and is released under the MIT License as open source.
