Girassol app icon — a sunflower

Girassol

See what's using your disk, as an interactive sunburst.

Girassol — Portuguese for sunflower, the flower that turns to follow the sun.

Coming soon to the Mac App Store

macOS 14 Sonoma or later · Apple silicon & Intel

Girassol showing a home folder as a sunburst: rings of colored wedges sized by disk usage, a sidebar listing Movies, Library, Pictures and other folders by size, and an inspector card for the selected Movies folder.

What it does

Sunburst & treemap

Two views of the same tree, a click apart. Rings or nested boxes, both sized by real on-disk usage.

Click to drill in

Zoom into any folder, follow the breadcrumb back out, and read a ranked list of the biggest items.

Reveal & reclaim

Jump to anything in Finder, or move it to the Trash (with confirmation) and watch the chart update.

Fast & accurate

Live progress while it scans. Real size on disk, hidden files included, hard links counted once, and it never wanders onto other drives.

Private by default

No telemetry, no accounts, no network connections. What you scan never leaves your Mac.

Native & sandboxed

Built in SwiftUI for macOS. It runs in Apple's App Sandbox and only reads the folders you choose.

Two ways to look

The same home folder as a nested treemap, with every folder drawn as a box containing its files and subfolders.
Treemap: nested boxes, one click away (⌘2).
Hovering the Photos Library in the sunburst: its branch stays in full color while the rest of the chart dims, and a label shows its name, 35.9 GB and 15.8%.
Hover any slice to spotlight its branch and see its size.

Screenshots use a demo home folder.
