Diskfern
See. Understand. Clean with confidence.
Diskfern helps you understand what's consuming storage on your Mac, find unnecessary files, and reclaim space without guessing.
Explore your disk through three visualization modes: Treemap, Sunburst, and List. Find large files, investigate System Data, and identify storage consumed by developer tools, Xcode, Docker, caches, build artifacts, and local AI models.
Diskfern performs scanning and analysis locally. Your files and scan results stay on your Mac. Nothing is removed without your approval.
Performance
Tested on an Apple M4 MacBook Air with 16 GB memory, Diskfern scanned 2.886 million files in 16.055 seconds. See the full benchmark methodology and results at https://www.diskfern.com/benchmarks.

- Investigate Unfamiliar Files: Use Disk Advisor on supported Macs to get on-device explanations of unfamiliar files and potential cleanup candidates.
Comments
Hey everyone, I built Diskfern after repeatedly running into storage problems while working across multiple development projects. Even with newer Macs, storage can fill up quickly with Xcode archives, simulator data, Docker files, build artifacts, caches, and other large files. Finding what was safe to remove often meant manually digging through folders. I wanted to build a native Mac app that makes this process easier to understand. Diskfern brings together disk visualization, developer-focused storage discovery, natural-language search, and guided cleanup. You can explore your storage, investigate unfamiliar files, and review cleanup candidates before removing anything. I’d love to hear your feedback, especially from Mac developers and anyone who regularly struggles with limited storage. Thanks for checking out Diskfern!
