CleanDevMac
Find and delete the dev caches eating your Mac's disk
cdm is an open-source macOS CLI that finds developer caches, build artifacts, Electron junk and orphaned app data — and never deletes anything without showing you the itemized list first. Pure bash. Zero telemetry. MIT.
CleanDevMac (cdm) is a terminal cleaner for macOS developers. It finds the caches and build artifacts that quietly eat your disk — Xcode DerivedData and DeviceSupport, Go/npm/pnpm/yarn/Cargo/Gradle/Maven caches, Electron and browser caches, Docker layers, orphaned app data — shows you what they are and how big, and deletes only what you tick.
There's no install step. It runs straight from a one-liner, scans, and hands you the TUI. When it exits, nothing of it is left on your Mac. There's a dry-run flag too, if you'd rather look before anything is touched.
The things I cared most about:
• Nothing is deleted without an itemized confirmation. You see the plan and the sizes, then type y.
• ~/Documents, ~/Desktop, ~/Downloads, ~/Pictures, ~/.ssh and iCloud Drive are never touched. That guard sits below the rule engine, so a rule can't opt out of it.
• Orphaned app data and git-ignored files go to the Trash, so they're recoverable. Caches are deleted outright — they regenerate on the next build.
• Zero telemetry. The only network call cdm ever makes is fetching its own rule JSON.
• Rules live in JSON, not code. Edit them, or point --patterns at your own set.
Pure bash, no dependencies, MIT, free — no paid tier, nothing held back.
Curious what it finds on your machine, and what it misses. Happy to answer anything.
