See exactly what's eating your Mac's disk.
DiskLoupe is a fast, beautiful macOS app that maps every byte on your drive so you can find and delete the space hogs in seconds.
Free to download · unlock the full scan with a license.
Reclaim gigabytes in minutes
DiskLoupe turns a cluttered, mysterious drive into a clear map you can actually act on.
Lightning-fast scans
A native, multi-threaded engine reads your entire drive in seconds — even a full 2 TB disk — without pegging your fan.
Visual treemaps & sunbursts
Every file and folder rendered to scale. Spot the 40 GB of forgotten downloads at a glance, then drill in with a click.
Delete with confidence
Reveal in Finder, move to Trash, or zap caches and node_modules in bulk. DiskLoupe never touches a file without your say-so.
Finds the hidden hogs
Surfaces the stuff Finder hides — system caches, Xcode derived data, old iOS backups, and bulky dependency folders like node_modules.
Private & offline
Everything runs locally on your Mac. No accounts, no cloud, no telemetry. Your file names never leave your machine.
Built for Apple Silicon
A universal binary tuned for M-series chips, with full support for Intel Macs and a crisp, native macOS interface.
A look inside
Designed to feel right at home on macOS.
Every file sized to scale — the big stuff looks big.
A live breakdown by file type, folder, and size.
Select, review, and reclaim — safely to the Trash.
