Diskly
A fast, native macOS disk usage visualizer.
Pick a folder and Diskly draws a squarified treemap of what's eating your space,<br>with a sortable size breakdown alongside it. Mark the junk, review it, send it to<br>the Trash in one pass.

Install
Download the latest build from GitHub releases,<br>unzip it, and drag Diskly to Applications.
The first time you run Diskly, macOS may show "Apple could not verify it is free of<br>malware." To bypass it: right-click Diskly in Applications → Open → Open in the<br>prompt, or go to System Settings → Privacy & Security and click Open Anyway .
Features
Treemap — every file sized by disk usage, colored by type; click to select,<br>double-click or the chevron to drill in, breadcrumb to navigate back.
Size breakdown — sidebar list of the current folder's contents, largest first.
Mark & clean — stage items for deletion (shown in red), review the total, then<br>Move to Trash together.
Fast scans — directories scanned in parallel across cores, with a live item<br>count and Cancel.
Build & run
make open # build and launch<br>make share # build a zip to share with others<br>make dist # signed + notarized release (needs config.mk)
Requires macOS 26+ and Xcode 26+. The app is sandboxed and only accesses folders<br>you explicitly choose.
