I built Diskfern because understanding what's eating up Mac storage shouldn't require digging through endless folders, guessing what System Data means, or paying just to see where your disk space went.
Diskfern is a native macOS storage analyzer built for everyday Mac users, developers, and power users.
It helps you discover exactly what's consuming your storage through three interactive visualizations: Treemap, Sunburst, and List.
But one feature I'm particularly proud of is natural-language file search. Instead of remembering filenames or navigating through complicated folder structures, simply type:
- "PDFs from last month"
- "Videos larger than 1 GB"
- "My invoices from last year"
- "Screenshots from this week"
Diskfern finds matching files so you can preview them with Quick Look or reveal them directly in Finder.
And this isn't locked behind a subscription.
The free version includes: - Unlimited disk scanning - Natural-language file search - Three interactive storage views - 44 Smart Highlights categories - Advanced file filters - Detailed file inspection and Quick Look
For developers, Diskfern can help uncover storage consumed by Xcode, iOS simulators, Docker, Node.js, Gradle, local AI models, build artifacts, caches, and forgotten development files.
I've also focused heavily on performance. In testing on an M4 MacBook Air with 16 GB RAM, Diskfern scanned approximately 2.9 million files in 16 seconds and searched 2 million indexed records in 2.35 milliseconds.
When you're ready to clean up, Diskfern Pro adds on-device AI cleanup guidance, batch cleanup, safe staging, and application uninstallation. Family extends the Pro toolkit to five Macs.
No forced subscription. No account required for scanning. No uploading your files for storage analysis.
I'm building Diskfern to make Mac storage management faster, more transparent, and accessible to everyone.
If you think Mac users deserve better storage tools, please support the launch. Every bit of support helps an independent developer get Diskfern in front of more people.
