100% data stays on your Mac · zero telemetry

One scan. Everything explained.

Nine visualizers, a duplicate finder that hashes real file contents, a dev-cache cleaner, snapshots, system monitor and reversible cleanup. Every feature is native, local, and available the moment you open the app.

Visualize

Nine ways to see your disk

Every visualizer reads the same scan, so you never rescan to change perspective.

Treemap

Squarified layout that shows proportions of any folder in one glance. Click to zoom, right-click to stage.

Folders

Classic expandable browser with live size columns and sorting — great for deep manual exploration.

List view

Flat, sortable, searchable table of everything under the focus — copy paths, batch-stage, open in Finder.

Top sizes

The ringleaders ranked by size with quick context actions. The fastest “give me the list” in the app.

Age map

Color folders by last-modified age to spot ancient archives and stale caches at a glance.

Sunburst

A nested ring chart that follows your focus — centre is the chosen folder, outer rings its children.

Flame graph

Budget-style bar rendering that emphasizes big, deep paths — find the long-tail monster deep down.

Bubbles

Circular packing of your largest items. Readable, shareable, and surprisingly calming for huge drives.

Mind map

Node-branch layout for tracing how a folder is composed without losing the parent context.

Analyze

Understand what’s growing

See changes over time, find real duplicates, and separate the stuff that matters from the noise.

Snapshots

Save the current state of a scan and diff it against today. See exactly which folders grew.

Duplicate finder

Hashes every file’s contents and groups lookalikes. Pick the keeper, preview the clones, reclaim the rest.

File type filters

Narrow by video, audio, docs, code, archives — or hide whole categories from every view.

Bloat filters

Collapse Node.js, Xcode and build-artifact trees across all visualizers so real data stays visible.

Insight inspector

Select any file or folder for a side panel with path, dates, byte counts and quick actions.

Logical vs on-disk size

See logical size and “size on disk” together, so clones and sparse files stop confusing you.

Clean

Reclaim space, safely

Everything you remove lands in the macOS Trash first. Nothing is deleted in the background, ever.

Quick Wins

Curated, right-now recommendations with byte counts. One click to queue, one more to review and trash.

App Uninstaller

Removes an app and its Application Support, Containers, Caches, Preferences, Logs, Saved State and WebKit data.

Dev Cache Cleaner

Twenty curated dev locations — DerivedData, simulators, SwiftPM, CocoaPods, Gradle, npm and more.

Screenshot renamer

Turn macOS screenshot names into descriptive, searchable filenames in one pass — with an undo-friendly dry run.

🗑

Trash, never delete

Every removal goes to the macOS Trash. You can always undo until the Trash is emptied.

Clean up now

Quick Wins ranks your candidates the moment a scan lands. Everything is staged first — nothing is ever deleted behind your back.

Track & monitor

See the whole machine

Live system insight alongside disk analysis — sampled every second, on your machine.

System monitor

Live CPU, memory, network and battery cards with sparklines, plus the top CPU processes.

In-app search

Search names and paths across everything scanned. Results in milliseconds, grouped by folder.

@

Floating search

⌘⇧Space from any app opens a global search window and jumps straight to matches on your Mac.

Trust

Private by construction

DiskInsight never sends your data anywhere. There’s nothing to leak because nothing leaves the process.

No account, no cloud

Install, scan, done. No sign-up, no sync layer, no remote servers involved at any point.

Zero telemetry

No analytics SDKs, no crash reporters, no usage pingbacks. If the network is off, nothing breaks.

Local by design

Scanning, search, snapshots and cleanup all run in your process. Data lives only in your app support folder.

For dev machines too

No firewall exceptions or certificates to install. Safe on work laptops, NDA environments and CI machines.

Exportable

Everything is yours: scan results are local files, snapshots stay in a folder you own.

Trash-only cleanup

Cleanup never deletes permanently. It goes to the macOS Trash first, so even a mistake is reversible.
