Crumb

macOS Disk Cleanup

Clean your Mac,
ruthlessly.

What It Cleans

Every byte has a story. Most of them ended a long time ago.

System Caches

macOS and third-party app caches that silently grow to absurd sizes. Crumb identifies stale cache data and clears it safely.

Avg. 8-15 GB

Logs & Diagnostics

Crash reports, diagnostic data, and system logs from months (or years) ago. Still sitting there. Still useless.

Avg. 2-6 GB

Browser Leftovers

Cached pages, extension data, download histories, and auto-fill databases from Safari, Chrome, Firefox, Arc, and more.

Avg. 3-8 GB

Build Artifacts

node_modules, .venv, target/, dist/, .next, .nuxt, __pycache__, .gradle, Pods, .dart_tool, .turbo, .angular, .svelte-kit, vendor, .expo, coverage, and more.

Avg. 5-20 GB

App Remnants

You dragged the app to Trash. The support files, plists, containers, and login items? Still here. Crumb finds them all.

Avg. 1-4 GB

Package Manager Caches

npm, Yarn, pnpm, pip, Cargo, Gradle, Maven, RubyGems, Go, CocoaPods, Homebrew, Dart pub, Composer, uv, and Bun. All in one sweep.

Avg. 2-10 GB
Features

Not a toy cleaner. A system-level tool built for people who care about their machine.

01

Deep Scan Engine

Goes beyond surface-level caches. Crumb traverses hidden directories, reads plist manifests, and identifies abandoned data with surgical precision — caches, logs, browser leftovers, app remnants, and build artifacts.

02

Build Artifact Cleanup

Finds and removes node_modules, .venv, target/, .next, .nuxt, __pycache__, .gradle, Pods, .dart_tool, .parcel-cache, .turbo, .angular, .svelte-kit, vendor, .expo, coverage, and more across all your projects.

03

Disk Usage Visualization

Color-coded breakdown of every gigabyte on your drive. See exactly what is hogging your storage — by category and size — so you can make informed decisions about what to keep and what to clean.

04

Xcode Cleanup

Targets Derived Data, Archives, Device Support files, and Simulator Caches. If you develop for Apple platforms, this alone can reclaim tens of gigabytes you forgot existed.

05

Package Manager Caches

Clears cached downloads from npm, Yarn, pnpm, pip, Cargo, Gradle, Maven, RubyGems, Go, CocoaPods, Homebrew, Dart pub, Composer, uv, and Bun. Every package manager, one sweep.

06

Dry-Run Mode

See exactly what Crumb would delete before a single byte is touched. Full preview with file sizes, paths, and modification dates. No surprises, no regrets.

07

Cumulative Savings

Tracks how much disk space you have reclaimed over time. See your total savings grow with each scan and clean — a running tally of gigabytes you have taken back.

08

Menu Bar & Tray Icon

Lives quietly in your macOS menu bar. Quick access to scan, check disk status, and clean — without opening the full app. Stays out of your way until you need it.

Deep Scanning

Powered by Mole CLI.

Crumb's cleaning engine is Mole: a deep scanner that traverses your filesystem with zero overhead. It maps orphaned caches, identifies stale build artifacts, and catalogs every hidden preference file left behind by uninstalled apps.

Mole operates at the system level with read-only scans by default. Nothing is deleted without your explicit confirmation. Every operation can be previewed, filtered, and reversed.
