Pearcleaner vs AppCleaner: Open Source App Uninstallers Compared

June 7, 2026·3 min read

Two Free Uninstallers with Different Origins

Pearcleaner and AppCleaner are both free app cleaner mac tools, but they come from different development philosophies. Pearcleaner mac is fully open source with its code available on GitHub. AppCleaner is freeware, meaning it is free to use but its source code is not public.

For privacy-conscious users, the open source app cleaner distinction matters. You can verify exactly what Pearcleaner does with your files by reading its code. With AppCleaner, you trust the developer's reputation.

AppCleaner: The Established Choice

AppCleaner by FreeMacSoft has been the go-to free Mac uninstaller for over a decade. Its drag-and-drop interface is about as simple as software gets. Drop an app on the window, see associated files, click Remove. Done.

It supports SmartDelete, which automatically shows associated files when you drag an app to Trash through Finder. This background monitoring feature makes it seamless to use once enabled.

AppCleaner handles the most common Library locations well: Application Support, Preferences, Caches, and Saved Application State. It is lightweight, fast, and trusted by millions of Mac users.

Reclaim Mac finds and removes junk files automatically.

Pearcleaner: The Open Source Challenger

Pearcleaner mac is a newer entrant that has gained attention for being fully open source. It offers a more modern interface with additional features like leftover file scanning, which finds orphaned files from apps you already removed.

The open source app cleaner model means the community can contribute improvements and verify security. For users who care about transparency, this is a significant advantage over closed-source alternatives.

Pearcleaner also scans deeper system locations than AppCleaner in some cases, catching files in Launch Daemons and system-level containers. However, being newer means it has had less time to mature and iron out edge cases.

Head-to-Head Cleaning Test

We tested both as app cleaner mac tools by installing and removing ten common applications. AppCleaner found an average of 8 associated files per app. Pearcleaner found an average of 10, catching a few extra files in system locations.

Both missed occasional files in less common locations. For most apps, the difference was negligible. For complex apps with system extensions, Pearcleaner's deeper scanning provided a slight edge.

Our Recommendation

Both are excellent free tools. AppCleaner wins on maturity and simplicity. Pearcleaner wins on transparency and deeper scanning. Either is a solid choice for basic app removal.

For users who want comprehensive cleanup beyond just app removal, Reclaim Mac combines uninstall cleanup with broader storage scanning in one free tool. It handles the leftover detection that AppCleaner lacks and the general cleanup that Pearcleaner does not focus on.
