PearCleaner is a free, open-source Mac app cleaner that goes far beyond simply deleting applications. When you uninstall an app on macOS, leftover files — preferences, caches, support files — quietly pile up and waste storage. PearCleaner finds and removes all of them, leaving your Mac genuinely clean. It also includes an orphaned file search to track down forgotten leftovers from apps you removed long ago.

What makes PearCleaner stand out is how much it packs in without charging a cent. Beyond basic uninstalling, it includes a Homebrew manager, a development environment manager, a PKG manager, and even an App Lipo tool that strips unnecessary architectures from universal apps to recover extra space. There's also a Sentinel Monitor that automatically cleans up when apps hit the Trash — so your Mac stays tidy without you lifting a finger.

The experience is polished too. You get a Finder extension for right-click uninstalling, drag and drop support, list or grid views, a theme system with custom colors, and adjustable search sensitivity. Whether you're a casual user who just wants clean uninstalls or a developer managing multiple environments, PearCleaner handles it all — and it's completely free.
