What DiskTree is

DiskTree is a native macOS utility that shows how files and folders use disk space. Its treemap represents each item as a proportional block, which you can inspect and open for deeper views. A one-click diagnosis checks more than 24 categories, including Xcode, Docker, Adobe, node_modules, and iOS backups. Developer-oriented rules also look for Xcode archives, device support files, Gradle caches, Maven repositories, and node_modules. The free plan includes the visual explorer, view-only diagnosis, and Reveal in Finder. Pro can move selected items to Trash, add a menu bar usage monitor, and send disk alerts. DiskTree says it reads file metadata, does not delete automatically, and keeps file names, folder structure, and disk contents on the device. It requires macOS 13 Ventura or later on Intel or Apple Silicon Macs. Pricing includes free access, Pro at $2.99 a month, $14.99 a year, or a 34.99 USD lifetime plan.

DiskTree suits Mac users who want a visual way to inspect storage, including developers with Xcode, Gradle, Maven, Docker, or node_modules data. It also fits people who want optional cleanup and disk alerts.
