LumaDisk vs SpaceMonger

LumaDisk is a disk space analyzer for macOS and Windows that maps a filesystem to show what is using storage. Its interactive sunburst and treemap views update during a scan. The app groups regenerable developer folders such as node_modules, /target,.next, and DerivedData, and groups duplicate files with one copy selected to keep. It also lists files of at least 100 MB that have not been opened for six months, a year, or two years. External drives are fully supported; network volumes can be analyzed read-only. Cloud support includes iCloud Drive, OneDrive, and Dropbox, while Google Drive is described as coming soon. The free plan keeps scanning and the sunburst view available. A LumaDisk license is listed at $6.89 a month, billed as a one-time payment rather than a subscription, and covers up to five Macs. Requirements are macOS 12 or later on Apple Silicon, or Windows 10 or later on x86-64 or ARM64. Reclaim permanently deletes files, with a ten-second undo window and safeguards against queuing system folders.

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.
