FOR MACOS
AppleTree
A high-speed disk space analyzer for macOS.
Scan a folder or an entire volume in seconds and see exactly what is eating your disk — as a sortable outline, a breakdown by file type, and an interactive treemap, all in sync.
Inspired by the speed of WizTree on Windows and the visualization style of GrandPerspective.

What it does
Scans at full speed
A parallel fts(3) traversal walks the filesystem natively and streams results as it goes, so the tree fills in while the scan is still running instead of blocking on a spinner.
Three views, always in sync
A size-sorted outline, a flat breakdown by file extension, and a labeled treemap. Select or hover in one and the others follow.
Delete straight to the Trash
Remove what you find with ⌘⌫ or the context menu. Totals across every view recompute instantly — no rescan — and confirmation is on by default.
Honest about what it skipped
When macOS blocks a folder, AppleTree tells you why — privacy-protected, system-owned, or plain permission denied — and only suggests Full Disk Access when it would actually help.
Notices changes underneath it
Files deleted or moved by Finder, Terminal, or anything else are flagged live in a completed scan, so the numbers on screen stay trustworthy.
Counts things once
Hardlinks, APFS clones, and firmlinked directories are de-duplicated, and a scan stays on one device — so totals reflect real disk usage.
WizTree for Mac
WizTree doesn’t run on macOS — its speed comes from reading the NTFS Master File Table, which APFS doesn’t have. If you’re looking for WizTree for Mac, AppleTree is that WizTree alternative: the same job built for this filesystem — a parallel scan, a size-sorted tree, a breakdown by file type, and a treemap, all kept in sync. Original software, not a port, and not affiliated with Antibody Software.
A GrandPerspective alternative
GrandPerspective is the classic Mac treemap for disk usage — AppleTree’s visualization is openly inspired by it. As a GrandPerspective alternative it adds the rest of the workflow around that treemap: a size-sorted tree and a file-type breakdown that follow your selection, a scan that fills in live instead of blocking, delete-to-Trash, and a live check when files change underneath a completed scan. Free under the GNU General Public License v3.0, not a fork, and not affiliated with the GrandPerspective project.
A DaisyDisk alternative
AppleTree is a free, open-source DaisyDisk alternative for Mac. DaisyDisk is built around a sunburst; AppleTree keeps three views in sync instead — a size-sorted outline, a breakdown by file type, and a labeled treemap — so you can go from “what’s huge” to “which files” without leaving the window. Scans stream in as they run, deletes go to the Trash, and when macOS hides a folder the app says so instead of silently under-counting. Nothing leaves your machine.

Nothing leaves your Mac
AppleTree has no account, no analytics, and no network calls. It runs in the macOS App Sandbox and reads only the folders you point it at. Scan results live in memory and are discarded when you close the window.
