Ledger for singleplayer
by Finsh
Ledger for singleplayer is a Fabric mod that records block changes in a single-player world, so players can look back at what was placed, broken or replaced.
What it does
The mod tracks modifications made to a singleplayer world. It logs blocks as they are placed, broken or replaced, and keeps those records for later lookup. Ledger for singleplayer is a port of a multiplayer logging mod, rebuilt to work without a server, and it uses the same logging system offline.
A log browser inside the game lets a player filter the records by block type and by time period. Installation needs Fabric API and Fabric Language Kotlin, and the mod runs on client and server, so a dedicated server and every player need it. Files are published for Fabric only, across three release versions, 26.1 – 26.3, under the MIT License, and the project is not open source.
Key features
Block change tracking
Placed, broken and replaced blocks are recorded automatically while the world is played.
In-game log browser
The browser filters entries by block type and by time period, so a specific change can be found quickly.
Same logging system offline
The logging system from the multiplayer original works in a single-player world without any server setup.
Low performance impact
The author describes the performance cost of the tracking as low, with no figures given.

Reviewing a build

Tracking a solo world
Players who want complete control over the history of their own world can keep a full record of changes.
Who it’s for: Players who run a single-player world and want a record of block changes without installing a server, and players who used the multiplayer original and want the same tools offline.
