Our verdict on ChunkCleaner
ChunkCleaner is a free, open-source command-line utility for Minecraft world administrators managing saved worlds and server world directories. It scans Java-style .mca region files, reads chunk InhabitedTime values, and identifies low-playtime regions for cleanup. Official releases provide Windows and Linux amd64 binaries, while desktop and self-hosted deployment suit solo administrators and small teams. Its best fit is basic Java region-file cleanup rather than general world editing.
The cleanup workflow offers useful control before files are changed. Dry-run mode allows a preview, and users can choose between per-chunk comparison and region-sum comparison. A configurable minimum inhabited-ticks threshold defines which regions qualify, while verbose processing output provides additional visibility during runs. Qualifying region files can be deleted or moved to a separate directory, giving administrators two cleanup paths depending on how they manage saved-world files.
ChunkCleaner’s narrow scope is its defining trade-off. It is designed for region cleanup and does not provide terrain editing or entity editing, so it is not a replacement for a broader Minecraft world editor. Its documented format and edition focus are Java-style .mca region files, with Windows and Linux amd64 binaries provided for local use. Choose ChunkCleaner when the task is removing low-InhabitedTime regions with configurable comparisons and a dry-run option; choose another tool when world content editing or a broader editing workflow is required.
