Mod Chunk Activity Tracker

Chunk Activity Tracker for Minecraft servers

Chunk Activity Tracker is a library mod for Minecraft Java Edition that records player activity by chunk, creating a persistent heatmap of how each area is used. It measures the time each player spends in a chunk, counts blocks placed there, and can preserve the original heightmap for later reference. It supports Fabric, Forge, and NeoForge on compatible versions including 1.20.1 and 1.21.1.

It works quietly in the background and adds no standalone gameplay features. Instead, it gives other mods reliable activity data for analysis, world management, or gameplay systems. Its optimized binary storage keeps data compact, even across very large worlds, making it a practical utility for a busy Minecraft server. At BoxToPlay, we make this kind of server enhancement easy to use.
