LumaDisk vs StorageRadar

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.

StorageRadar is a macOS desktop tool for examining disk use across files, folders, and applications. It reports application sizes and file-type breakdowns, with exportable reports. Treemap and Sunburst views present storage distribution, while local snapshots and history retain scan records. The Free plan costs nothing and includes deep storage scanning, preview access across Disk Analysis, Duplicate Review, App Uninstaller, and Dev Cleanup, plus permissions diagnostics and local MCP integration. The Core plan is listed at $9.99 a month, with a one-time purchase noted. Its added actions include moving items to Trash with an undo window, permanent deletion, applying storage cleanup, and applying app uninstalls. The Developer plan is listed at $19.99 a month, also with a one-time purchase noted. It adds Dev Cleanup actions, ecosystem profiles, report comparisons over time, and JSON, Markdown, and CSV export. The listed desktop platform is macOS.
