Spec score 8.9 #4 of 105 in Disk Space Analyzers

What it is

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.
