Features

Everything you need.
Nothing you don't.

Sunburst chart

Full-disk scan completes in seconds, not minutes. Perceptually-uniform color ramp — your biggest files leap out the moment it's done.

Build-cache radar

node_modules, /target, .next, DerivedData — auto-detected and grouped. Reclaim gigabytes in one click.

Zoom any wedge

Drill into any folder to re-layout the chart on that subtree. Breadcrumb trail keeps you oriented.

Cloud drive support

iCloud Drive, Google Drive, Dropbox — LumaDisk sees them all. Find out exactly how much local storage your cloud sync folders consume before they fill your disk.

Ships with macOS + Windows

Built with Rust and GPUI — the same GPU-accelerated stack powering Zed. Runs native on Apple Silicon and Windows ARM64. No Electron, ever.

Private by default

Nothing leaves your machine.

mapped in seconds.

Cloud Support

Scan any drive,
cloud storage included.

LumaDisk scans every drive connected to your machine — internal SSDs and HDDs, external drives, USB sticks, SD cards, and network volumes. And unlike most tools, it doesn't stop at your local storage: synced cloud folders are mapped with the same sunburst detail, so you always know exactly what's eating your quota.
