Nine ways to see your disk
Every visualizer reads the same scan, so you never rescan to change perspective. All free.
TreemapFree
Squarified layout that shows proportions of any folder in one glance. Click to zoom, right-click to stage.
FoldersFree
Classic expandable browser with live size columns and sorting — great for deep manual exploration.
List viewFree
Flat, sortable, searchable table of everything under the focus — copy paths, batch-stage, open in Finder.
Top sizesFree
The ringleaders ranked by size with quick context actions. The fastest “give me the list” in the app.
Age mapFree
Color folders by last-modified age to spot ancient archives and stale caches at a glance.
SunburstFree
A nested ring chart that follows your focus — centre is the chosen folder, outer rings its children.
Flame graphFree
Budget-style bar rendering that emphasizes big, deep paths — find the long-tail monster deep down.
BubblesFree
Circular packing of your largest items. Readable, shareable, and surprisingly calming for huge drives.
Mind mapFree
Node-branch layout for tracing how a folder is composed without losing the parent context.
Understand what’s growing
See changes over time, find real duplicates, and separate the stuff that matters from the noise.
SnapshotsPro
Save the current state of a scan and diff it against today. See exactly which folders grew.
Duplicate finderPro
Hashes every file’s contents and groups lookalikes. Pick the keeper, preview the clones, reclaim the rest.
File type filtersFree
Narrow by video, audio, docs, code, archives — or hide whole categories from every view.
Bloat filtersFree
Collapse Node.js, Xcode and build-artifact trees across all visualizers so real data stays visible.
Insight inspectorFree
Select any file or folder for a side panel with path, dates, byte counts and quick actions.
Logical vs on-disk sizeFree
See logical size and “size on disk” together, so clones and sparse files stop confusing you.
Reclaim space, safely
Pro unlocks cleanup: everything you remove lands in the macOS Trash first. Nothing is deleted in the background, ever.
Quick WinsPro
Curated, right-now recommendations with byte counts. One click to queue, one more to review and trash.
App UninstallerPro
Removes an app and its Application Support, Containers, Caches, Preferences, Logs, Saved State and WebKit data.
Dev Cache CleanerPro
Twenty curated dev locations — DerivedData, simulators, SwiftPM, CocoaPods, Gradle, npm and more.
Screenshot renamerPro
Turn macOS screenshot names into descriptive, searchable filenames in one pass — with an undo-friendly dry run.
Trash, never deletePro
Every removal goes to the macOS Trash. You can always undo until the Trash is emptied.
Clean up now
Quick Wins is free to read — the one-click cleanup that stages everything first is Pro, so nothing ever deletes behind your back.

Live system insight alongside disk analysis — sampled every second, on your machine. Free.
System monitorFree
Live CPU, memory, network and battery cards with sparklines, plus the top CPU processes.
In-app searchFree
Search names and paths across everything scanned. Results in milliseconds, grouped by folder.
Floating searchFree
⌘⇧Space from any app opens a global search window and jumps straight to matches on your Mac.
Private by construction
DiskInsight never sends your data anywhere. There’s nothing to leak because nothing leaves the process. Free on every tier.
No account, no cloudFree
Install, scan, done. No sign-up, no sync layer, no remote servers involved at any point.
Zero telemetryFree
No analytics SDKs, no crash reporters, no usage pingbacks. If the network is off, nothing breaks.
Local by designFree
Scanning, search, snapshots and cleanup all run in your process. Data lives only in your app support folder.
For dev machines tooFree
No firewall exceptions or certificates to install. Safe on work laptops, NDA environments and CI machines.
ExportableFree
Everything is yours: scan results are local files, snapshots stay in a folder you own.
Trash-only cleanupFree
Cleanup never deletes permanently. It goes to the macOS Trash first, so even a mistake is reversible.
