What DiskAtlas is
DiskAtlas is a Mac disk space analyzer and system monitor with a zoomable treemap for exploring storage from the root volume into folders. It scans files, folders, and apps, and highlights developer storage such as Xcode DerivedData, CocoaPods caches, Docker overlay2 data, Cargo artifacts, Python virtual environments, and node_modules. It can find support, group container, cache, and preference files left behind by removed apps. For APFS clones and hard links, it reports logical and unique bytes. A menu bar monitor tracks CPU activity, memory pressure, and disk I/O, with disk pressure alerts. Pro adds an OCR screenshot inbox and on-device AI cleanup recommendations. Scans run locally, and the site says the app has no telemetry, analytics SDKs, or cloud uploads. It supports macOS 14 and 15 on Apple Silicon M1–M4 and Intel Macs. The Community Edition is free forever; Pro is $5 a month, includes lifetime updates, and covers up to three personal Macs.
