SpaceMap review
A focused, free Mac treemap analyzer for finding large folders and files.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SpaceMap is a native macOS disk-space analyzer for people who want a visual way to inspect folders and volumes. Its squarified treemap displays files as proportionally sized tiles, while directory drill-down, breadcrumbs, filtering, sorting, and search help narrow attention to specific areas. Drag-and-drop scanning and recent-scan persistence suit solo users and small teams that regularly review local storage. It supports Apple Silicon and Intel Macs running macOS 13 or later.
The free edition is MIT licensed and available indefinitely, making SpaceMap a straightforward option for Mac users who want core scanning without a recurring plan. It includes concurrent scanning, five built-in themes, folder scanning, recent scans, and the treemap workflow. Finder integration and Quick Look make file inspection fit naturally into a desktop workflow, while sandboxed operation allows scanning of selected folders and external drives without full-disk access. Support is provided by email, and the product lists GDPR compliance.
SpaceMap keeps its focus on visual folder and file navigation rather than broader storage classification. The published feature set does not include app-size or file-type breakdowns, so users seeking those views should consider a more specialized alternative. A forthcoming Pro edition is described with scan caching, scan comparison, CSV export, custom themes, and priority email support. That makes SpaceMap most suitable for Mac users who value a simple free treemap and selected-folder scanning; it is less suitable for buyers who need cross-platform coverage, deeper classification, or an established paid-tier workflow today.
