Hey Product Hunt! I’m Elem, the indie developer behind CacheMelt.

Like many developers and creators working on 256GB or 512GB MacBooks, I was constantly getting the dreaded "Your disk is almost full" alert.

When digging into ~/Library, I discovered that over 50+ GB was secretly held hostage by:

• Xcode DerivedData, Archives, and orphaned iOS Simulator runtimes • Dormant DAW Audio Plugins (gigabytes of Avid AAX plugins installed without Pro Tools, legacy VST2s, and AU validation caches) • npm global tarballs & temporary npx packages • Android Studio & Gradle build artifacts • Staged background application updaters & sandbox residues

While you can run blind rm -rf commands in Terminal, deleting certain cache folders completely can break future xcodebuild, npm, or DAW sessions because expected folder hierarchies disappear.

That’s why I built CacheMelt — a native, safe, local-first utility built specifically for developers, audio engineers, and Mac power users.

What makes CacheMelt different:

Non-Destructive Skeleton Recreation: It purges disposable build garbage but automatically recreates empty folder skeletons so your build tools and audio hosts never crash with missing directory errors.
Developer & DAW Aware: Cleans code build artifacts AND detects dormant audio plug-in formats without touching your active project files.
Broad macOS Compatibility: Fully supports macOS 12 (Monterey), 13 (Ventura), 14 (Sonoma), and 15 (Sequoia) on both Apple Silicon and Intel.
100% Native & Lightweight: Built purely with Swift/SwiftUI (~3.5 MB binary — zero Electron bloat, 0.1s launch time).
Apple Notarized: Fully signed and notarized with an official Apple Developer ID.
No Subscriptions: One-time purchase, lifetime license for up to 5 personal Macs.
