What LumaDisk is

LumaDisk is a disk space analyzer for macOS and Windows that maps files and folders to show what is using storage. Its interactive sunburst and treemap charts update as a scan runs, and it can scan external drives. The app groups regenerable developer folders such as node_modules, /target, .next and DerivedData. It also groups duplicate files with one copy selected to keep, and lists files of at least 100 MB that have not been opened for six months, a year or two years. Network volumes can be analyzed in read-only mode. LumaDisk supports iCloud Drive, OneDrive and Dropbox; Google Drive is described as coming soon. The app says local scans make no network requests and that it does not send file names, contents, folder listings, scan results or in-app usage statistics. Scanning and the sunburst view remain free. The listed license is $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.
