LumaDisk vs Space Wizard

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.

Space Wizard scans files and folders on Windows, macOS and Linux, including external drives. Scan locations can include selected folders, whole drives, multiple drives, and shared or NAS folders. It can look for matches using SHA-256 content hashing, byte-for-byte exact matching, or recursive folder-content matching, and supports sending items to the Recycle Bin or Trash. Its Free plan costs nothing, is free forever, requires no card and covers the home drive up to 100 GB per scan. The product does not offer a treemap view, application sizes or a file-type breakdown. It also lacks automatic selection, so scan locations and matching methods are chosen by the user. Space Wizard is cross-platform and comes from a maker founded in 2024 and headquartered in Kragujevac, Serbia.
