Features

Built for the messy, real-world developer Mac.

Storage Cleaner was designed around the actual data trails left by Swift, Node, Docker, Flutter, Android, Xcode, and local AI tools — not the things the App Store "optimize your Mac" apps think you have.

See every gigabyte, mapped to a domain

A single, focused dashboard breaks your disk into Apple, Web, Docker, Mobile, AI & ML, Media, Browser, and more — so you instantly know which world is using how much.

Inactive projects, surfaced automatically

Find projects you haven’t opened in weeks or months. See their size, last activity, and reclaim the disk with one click — without touching active work.

Simulators, emulators & device support

Audit iOS simulator runtimes, Android system images, and per-device support files. Apple runtimes re-download; Android images move to the Trash, restorable.

Docker, OrbStack & Colima, untangled

Inventory images, stopped containers, dangling layers, builder cache, and volumes across Docker, OrbStack, and Colima. Remove what’s safe, keep what’s not.

Large files, no more guesswork

A 10 MB floor scanner across Desktop, Downloads, Documents, Pictures, and Movies. PDFs, datasets, disk images, archives, exports — the actual culprits.

Duplicate photos, videos & documents

Byte-identical duplicates, repeated exports, edited copies, and screen recording backups — grouped with full paths and sizes so you can decide.

System junk, browser cache & logs

Temporary files, crash reports, stale logs, Safari / Chrome / Edge / Arc / Firefox caches, and leftover DMG / PKG / IPA installers — surfaced with provenance.

Build & package caches, cleaned safely

npm, pnpm, yarn, Gradle, Maven, Composer, pip, Poetry, conda, Cargo, Go module cache, NuGet, and pub cache — sized and separated by safe-to-clear.

Detection coverage

15+ storage domains, one inventory.

Every scanner is a thin, typed, protocol-driven component that reuses a small set of high-performance engines. No black-box heuristics, no surprise deletions.

How it works

From cluttered to cleaned in four calm steps.

No upsells, no "boost your RAM" nonsense. The app respects your machine: it scans read-only, explains every byte it touches, and keeps a full audit log.

  1. STEP 01

    One scan, every domain

    A single click walks DerivedData, node_modules, Docker layers, sim runtimes, AI caches, browser caches, Trash, and more — concurrently and cancelable.

  2. STEP 02

    Inspect with full paths

    Every finding shows the exact path, size, count, and provenance. Safe-to-clear items are flagged; user-created media stays in review.

  3. STEP 03

    Preview, then clean

    A live preview summarizes the recovery estimate and what will be removed. Confirm to send everything to the Trash — never a hard delete.

  4. STEP 04

    Audited, recoverable

    Every cleanup produces a detailed audit record. Anything in the Trash can be restored in a single click from Finder.

Safety model

Destructive operations deserve obsessive care.

Storage cleanup is one of the most dangerous things a Mac app can do. The product is engineered around the principle that nothing should ever be permanently destroyed by accident — and that the user should always know exactly what is about to happen.

Read-only by default

Scanning never moves, modifies, or deletes a file. Cleanup is an explicit, confirmable action.

Trash, never hard delete

Everything the app removes goes to the macOS Trash. Restore any item from Finder in a click.

Safe vs. review gating

Caches, build outputs, and runtime duplicates are marked Safe. Media, photos, screenshots, APKs, and Trash stay in review.

Path-validated, never stale

Before any cleanup, every path is re-validated. If a file moved or changed size, the action is skipped, not guessed.

Streaming, cancelable scans

A 1 TB disk shouldn’t lock your Mac. The scanner streams results and honors ⌘. (Cancel) at any moment.

Full audit trail

Every action is logged with a timestamp, target, size, and outcome. Exportable from Settings.

Pricing

Free forever, Pro when you need it.

The scanner and inventory are unrestricted. Pro unlocks the automation and policy tools for developers who want cleaning to happen quietly, in the background. Pick the plan that fits — or pay once and never think about it again.
