DiskScout maps your disk six different ways and tells you what each folder is and whether it's safe to delete. Cleanup goes Trash-first, with in-app restore until you empty the Trash.

Every file as a rectangle, sized by bytes. Hover for size and safety, double-click to dive in.
Knowing that ~/Library/Developer is 40 GB is not the same as knowing whether you can delete it. DiskScout closes that gap on every click.
DerivedData, CoreSimulator, Docker.raw, MobileSync backups, Ollama models, CloudKit caches… 140+ known paths get a plain-English “what is this” and a “what happens if I delete it”.
Safe · Probably safe · Careful · SystemThe moment a scan lands you get a ranked plan: biggest wins first, sorted by safety. Stage what you agree with, clean once.
One click per winEvery node_modules, .venv, target/, Pods and .next is grouped by project and dated by the newest source file. Untouched 60 days? Reclaim it, and DiskScout shows the command to restore it.
Built for developersThe mystery bar in macOS Storage settings, split into snapshots, swap, caches, logs, iPhone backups and Docker, each with an action. Thin Time Machine local snapshots from inside the app.
The #1 Mac storage questionFinds fully-downloaded iCloud Drive files and evicts the local copy. Space comes back, files stay in iCloud and re-download on open.
Nobody else does thisFile cleanup moves items to the Trash and keeps a history. Restore puts them back before the Trash is emptied. Empty Trash, iCloud offload and snapshot thinning are separate, clearly labelled actions.
Sleep wellEvery app is listed with its true footprint: bundle plus the caches, preferences, containers, HTTP storage and logs it scattered across your Library. Uninstall Completely takes the whole set, and tells you when you last used the app.

Some people find the big folder by area, some by ranking, some by date. Treemap, Sunburst, Flame, Top Sizes, Folders and Age Map all read from one scan, so switching is instant.

Bytes split by last-modified date, and a Big & Untouched list of files over 100 MB nobody has opened in a year. Stage the whole set with one click.

Byte-for-byte SHA-256 matching (size buckets, then sample, then full hash, so it's fast). Plus a list of DMGs and PKGs in Downloads whose app is already in /Applications.

Watch free space recover while you clean. CPU, memory, network and the processes doing the work, ranked. Save a snapshot today, compare next month, and see exactly which folder grew.

One click renders a clean 1600×900 card of your scan, folder names blurred if you like, ready to post. Compare notes with friends on what's eating their Macs.

The visual analyzers show size. The cleaners want a subscription. DiskScout is the one that explains, and it's bought once.

Feature notes from public product pages as of September 2026. If anything here is out of date, email us and we'll fix it.
No subscription, no account, no upsell inside the app. One payment, one Mac at a time, move it whenever you like.
Payments, VAT and invoices are handled by Dodo Payments (cards, Apple Pay, Google Pay, PayPal, UPI). Your licence key shows on screen right after checkout and arrives by email.
It scans a drive or folder and maps every byte, then gives you six ways to look at the result. Click anything and the inspector tells you what it is, whether it's safe to delete, how much APFS compression is saving you, and the ten largest things inside. Stage items for cleanup, review the list, and move them to the Trash in one go.
Those show you size. DiskScout also tells you meaning: 140+ known folders get a plain-English explanation and a safety grade, developer junk is grouped by project and dated, “System Data” is decoded into actionable pieces, and iCloud files can be offloaded instead of deleted. Everything goes to the Trash first with an in-app Restore.
Scan time depends on file count, storage and macOS permissions. Scanning runs in parallel, and all six views share one in-memory tree. The app shows the measured file count and elapsed time after each scan.
No. Scanning, hashing and duplicate matching all happen locally. There is no account, no sync, no analytics. The only network calls are a licence check with Dodo Payments and an optional update check you can turn off.
Not on its own. Items go to a staged list you review first; system-critical paths cannot be staged at all; and cleanup moves things to the Trash rather than deleting. The Reclaim tab keeps a history with a Restore button.
Without it, macOS hides Mail, Messages, Safari and a few Library folders, so totals come out low. DiskScout shows a banner with a one-click link to the right System Settings pane. It is optional.
One at a time. Moving to a new Mac: open Settings on the old one, choose Deactivate This Mac, and the key is free to activate elsewhere.
Only to activate. After that, DiskScout re-checks the key in the background when it can, and keeps working for two weeks without any connection.
Yes. The app ships as a universal binary for Apple silicon and Intel, macOS 14 Sonoma or later.
Email support@piplistudio.com from the address you bought with and we'll resend it.
One scan, and the folder quietly holding thirty gigabytes stops being a mystery.
