What's the best CleanMyMac alternative for developers?
For developers, the best CleanMyMac alternative is a cleaner that understands your stack instead of treating dev caches as generic "application junk". GRUJ knows Xcode DerivedData, ~/.gradle/caches, Docker build cache, AVDs, .pub-cache, Rust target/ and the pnpm store by name — and ships a CLI for CI and scripts, which CleanMyMac doesn't. It runs €19.99/year vs CleanMyMac's subscription (see their site for current pricing).

CleanMyMac is a great generalist. It just isn't dev-first.
Credit where it's due: CleanMyMac is a polished all-rounder — system junk, an uninstaller, malware scanning, maintenance. Its System Junk module even clears Xcode DerivedData, the module cache and iOS Device Support. But to it, your dev caches are just "application cache": it doesn't distinguish ~/.gradle/caches from your gradle.properties, a Docker build cache from a volume holding your database, or a reusable simulator runtime from a dead one. And there's no CLI — you can't drop it into a pre-commit hook or CI. GRUJ is the opposite trade: not a Swiss-army knife with an antivirus bolted on, but the dev scalpel that knows every stack by name.
gruj scan — by stack, not by guess
GRUJ walks every ecosystem on your Mac: Xcode (DerivedData, Archives, DeviceSupport, runtimes), Android (~/.gradle/caches, wrapper/dists, AVDs), Flutter .pub-cache, node_modules + pnpm/bun stores, CocoaPods, Docker, Rust ~/.cargo + target/, Homebrew cache. Each item shows its real on-disk size — no vague 'junk' total.
Pick on two axes
Choose by tool (Xcode, Gradle, Docker, node) or by type (cache, build, download). Drop three stale AVDs, keep the one you test on; prune the Docker build cache but never the volume with your DB. CleanMyMac groups it all as one bucket; GRUJ lets you decide per target.
gruj clean — or wire it into CI
Confirm and clean. GRUJ only deletes paths on its regenerable allowlist and asks first. Because there's a CLI (gruj scan / clean / prepare / doctor), the exact same job runs in a script or a CI job — something a GUI-only cleaner like CleanMyMac simply can't do.
Per-stack, not generic 'application cache'
CleanMyMac's System Junk sweeps Xcode DerivedData and a few caches as generic junk. GRUJ knows each stack by name: Gradle's modules-2 vs wrapper/dists, CocoaPods download cache vs Pods vs spec repos, Rust registry vs target/, the pnpm content-addressable store. Deeper coverage, fewer blind spots.
A real CLI for CI and scripts
gruj scan / clean / prepare / doctor run in the terminal, headless. Put it in a pre-commit hook, a cron job, or a CI step to reclaim runner disk. CleanMyMac is GUI-only — there's no way to automate it. This is the single biggest dev difference.
Docker: orphaned, not your data
docker system prune by hand won't touch volumes by default, and -a --volumes can wipe a database. GRUJ targets reclaimable images, stopped containers and build cache — the regenerable stuff — and leaves data volumes alone. A generic cleaner doesn't even see Docker's internal layout.
Knows what's config, not just cache
Delete ~/.gradle wholesale and you nuke gradle.properties and init scripts; rm -rf the wrong CoreSimulator folder and you lose simulator state. GRUJ's allowlist separates regenerable caches from config and data, so it clears the cache and leaves your settings.
Cheaper, and an honest lifetime
GRUJ is €19.99/year or €59 once ; CleanMyMac is a subscription, and its one-time license covers only the current major version. No antivirus you didn't ask for — just the dev cleaner.
Everything CleanMyMac does for code, in one scan
DerivedData, Gradle, node_modules, Docker, Flutter, CocoaPods, simulators, Homebrew, $TMPDIR and ~/.cache — one pass across all of them. No running a separate command or module per ecosystem, and the freed space is shown before you confirm.
GRUJ vs CleanMyMac, for developers
| GRUJ | CleanMyMac | |
|---|---|---|
| Per-stack dev knowledge | Deep — Gradle, Docker, Rust, CocoaPods, pnpm by name | Treats dev caches as generic 'application cache' |
| CLI for CI / scripts | Yes — gruj scan / clean / prepare / doctor | No — GUI only |
| Docker (images, build cache, volumes) | Clears orphaned/regenerable, never data volumes | Not a Docker-aware module |
| Price (1 Mac) | €19.99/year · €59 lifetime | Subscription · one-time = current major only |
| Scope | Dev-focused: caches, builds, uninstaller, leftovers | General all-rounder + malware/antivirus |
| When CleanMyMac is the better pick | — | You want a polished general Mac cleaner + AV, not a dev tool |
FAQ
What's the best CleanMyMac alternative for developers?
For developers it's a cleaner that understands each dev stack and has a CLI — that's GRUJ. It clears Xcode DerivedData, ~/.gradle/caches, Docker build cache, node_modules, AVDs and the pnpm store by name, and gruj scan/clean run in CI. CleanMyMac is a fine general cleaner but treats dev caches as generic junk and has no CLI.
Is GRUJ cheaper than CleanMyMac?
Yes. GRUJ is €19.99/year or €59 lifetime. CleanMyMac is subscription-based and generally pricier for a single Mac, and its one-time license covers only the current major version; GRUJ's €59 lifetime includes updates.
Does CleanMyMac clean Xcode and developer caches?
Partly. CleanMyMac's System Junk module does clear Xcode DerivedData, the module cache and iOS Device Support, and lists some npm/Docker caches as application cache. But it doesn't go per-stack — it won't distinguish Gradle's wrapper dists, CocoaPods spec repos, Rust target folders or Docker volumes-with-data from regenerable cache.
What does GRUJ do that CleanMyMac doesn't?
Two things mainly: per-ecosystem depth (it knows ~/.gradle/caches vs gradle.properties, Docker build cache vs data volumes, the pnpm store, Rust target/) and a CLI (gruj scan/clean/prepare/doctor) you can run in scripts and CI. CleanMyMac is GUI-only and treats dev caches generically.
Is GRUJ safe? Will it delete my code or my Docker databases?
No. GRUJ only deletes paths on a fixed regenerable allowlist (caches, builds, artifacts) and always asks you to confirm first. For Docker it targets orphaned images, stopped containers and build cache — never your data volumes. Your repos, source and config are never in the plan.
Is CleanMyMac worth it for developers?
It's worth it if you want a polished general Mac cleaner with an uninstaller and malware scanning. If your disk fills up mainly with dev junk — Xcode, Gradle, Docker, node_modules — a dev-first tool with per-stack knowledge and a CLI like GRUJ fits better and costs less.
Can't I just clean dev caches by hand instead?
You can — rm -rf ~/Library/Developer/Xcode/DerivedData, docker system prune, pnpm store prune, cargo cache --autoclean all exist. But that's about ten commands across ten ecosystems, several are dangerous blind (rm -rf ~/.gradle, docker prune --volumes), and you must know what's regenerable vs config. GRUJ packages that knowledge into scan → pick → confirm.
Is GRUJ on the Mac App Store like some cleaners?
No. The App Store sandbox forbids exactly what a real cleaner does — launching tools like docker and xcrun and deleting across the disk. GRUJ is a direct download, signed and notarized by Apple, the same distribution model CleanMyMac uses outside the App Store.
