What Neodisk is

Neodisk is a free, open-source, read-only disk-space visualizer for macOS 14 or later, with Linux also listed as a platform. It maps local disks and cloud drives by scanning files, folders, and apps, then presents storage through Cushion, Flat, and Sunburst views. Treemap visualization and file-type breakdowns show how space is distributed. Scans and visualizations are processed locally, so scan data and file names remain on the Mac. An optional Google Drive connection displays storage quota and file metadata using read-only access; Neodisk says it does not read, download, or modify file contents. Google data supports on-device visualization, search, and analysis, not advertising, analytics, or AI/ML training. Tokens are stored in macOS Keychain, and signing out revokes access and deletes cached data. Neodisk says it has no analytics, tracking, or data collection. Installation is available through Homebrew.
