CoVisualiser
by spzla
CoVisualiser is a client-side administration tool that displays CoreProtect lookup results in the world, so server staff can read block changes without flooding the chat.
What it does
Running CoreProtect lookups in the game chat can produce long walls of text. CoVisualiser moves those results out of the chat and draws them in the world, where each change appears at its position, with a cleaner interface for reading them. Results can be collapsed into veins, grouping connected changes into one entry, and the changes can be viewed over time to follow how a build or a grief event unfolded.
The mod is aimed at staff and moderators who investigate block history on a server running CoreProtect. Installation needs Fabric API on Fabric, and the mod is listed for Fabric alone across 3 release versions, 1.21.11 – 26.3. Its latest file is 0.2.1 for 26.3 on the beta channel. CoVisualiser is open source under the GNU Lesser General Public License v3.0 only and runs on the client alone, so the server does not need it.
Key features
In-world result rendering
Lookup results are drawn at their block positions in the world rather than printed as chat lines.
Reduced chat spam
Because the results leave the chat, long CoreProtect lookups no longer fill the message window.
Changes over time
Results can be viewed across a timeline, so a sequence of edits in one area is easier to follow.
Collapsed veins
Connected results can be grouped into a single collapsed entry, reducing clutter in dense areas.

Use cases
Investigating grief
A moderator can look up who changed a region and see the affected blocks drawn in place.
Reviewing builds
Staff can step through the history of a construction to check what was altered and when.
Who it’s for: Server staff and moderators who use CoreProtect to trace block history and want a clearer way to read lookup output. Players who only join a server do not need it.
How it compares
Watdad is a Fabric mod with the same client-side only environment and MIT License, covering 1.21.4 – 26.2, so it does not reach 26.3. AltChecker is server-side only, targets 1.21.1 under GNU General Public License v2.0 only, and handles account checks rather than lookup display. GriefLogger is a server-side mod that also works on Forge and NeoForge across 1.19.2 – 26.2, under the Apache License 2.0.
