Space Gremlin review
A focused Mac disk analyzer with visual cleanup tools at a low one-time price.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Space Gremlin is a macOS disk-space analyzer for solo users and small teams that want a visual overview of local storage. Its treemap visualization represents files and folders graphically, while folder zooming and path navigation help users move from a broad view into specific locations. It can scan connected hard drives and external drives, show hidden files through a visibility toggle, and open selected items in Finder or Quick Look.
The published plan is a single Space Gremlin offering priced at $4.99 as a one-time purchase. It includes file and folder scanning, treemap visualization, compression, and the ability to move items to Trash. The product is distributed as a Mac App Store utility, and its listed support channels are email and documentation. A Polish Mac App Store listing displays 24.99 zł, so the storefront and currency are relevant when checking the purchase price.
Space Gremlin’s standout strength is its narrow, visual approach to cleanup. An ignore list can exclude selected files and folders, while Pro/Admin mode supports restricted-file scanning and broader drive access. These controls suit Mac users who prefer inspecting storage visually rather than working from reports or integrations. The trade-off is limited scope: there is no free plan, the product is desktop-only for macOS, and it does not provide reports or integrations. Choose it for straightforward local and external-drive inspection with basic cleanup actions; choose an alternative if you need broader platform coverage, connected workflows, or reporting.
