Neodisk vs SpaceMonger

Neodisk is a free, open-source disk space analyzer for macOS and Linux. It scans files, folders and applications, then presents storage usage in treemap, sunburst and outline views. Zooming, folder navigation, fuzzy search and keyboard navigation help you move through a scan. Analysis includes largest-file discovery, file-type statistics, an age heatmap and duplicate finding verified with content hashes. Neodisk is read-only: available file actions are revealing an item in Finder or Files, opening it and copying its path. Completed scans persist as snapshots that can be reopened. On macOS, the Changes tab records additions, deletions, renames and size changes since the previous scan. Optional Google Drive access reads quota and metadata without reading, downloading or changing file contents. macOS requires version 14 or later on Apple silicon or Intel. Linux AppImages support x86_64 and ARM64, but Linux lacks duplicate and changes tabs, cloud-drive scanning and incremental rescans.

SpaceMonger is a Windows utility for finding and managing storage on PCs and shared networks. It scans and maps files and folders, then displays storage in a treemap to help identify large items. A file-type breakdown and flexible search by size, type, or custom criteria can narrow what to review. Users can build changing cleanup lists and copy, move, or delete files from them. SpaceMonger does not include application sizes in its storage view. Its listed system requirements cover Windows 2000, XP, Vista, 7, 8, 8.1, and 10. The purchase page lists English and Spanish as included languages and 30 days of support. The software is paid, has a 30-day trial, and has no free plan. Stardock says it has operated as a software development company since 1991 and specializes in Windows desktop customization and productivity software.
