KlarityDisk

Klarity is a disk space analyzer for macOS that shows where your storage went as a treemap: every file and folder is a rectangle sized to scale, so the biggest items are visible at a glance instead of being found one folder at a time. An icicle view compares folders at the same depth, and an age heatmap colours everything by last-modified date so large-and-old stands out.

A Large Files list shows the 200 biggest files across a scan, with filters by type and by age (older than 30 days, 90 days, 6 months, a year). Right-click anything to reveal it in Finder or move it to the Trash. Trash always asks first, and anything over 1 GB needs a slide to confirm. Klarity never empties the Trash and never touches the sealed system volume.

Scans any mounted volume, including external and network drives, and includes a live RAM monitor in the menu bar. Six colour themes. Runs 100% locally: no accounts, no analytics, no cloud, no telemetry.

Requires macOS 14 Sonoma or later, Apple Silicon and Intel. $6.99 one-time on the Mac App Store, no subscription.
