Questions & Answers

As answered by people managing DiskFox and GrandPerspective.

What makes your product unique?

DiskFox's answer

Most disk tools show what's big right now. DiskFox keeps a history of every scan, so it shows what grew, when, and the likely cause, and tells you when something you cleaned comes back. Where macOS hides a size, it says so instead of guessing.

Why should a person choose your product over its competitors?

DiskFox's answer

Choose it if you want to know why your storage keeps filling up, not just what's big today. DaisyDisk maps your disk as it is now; CleanMyMac does far more but has one-click cleaning. DiskFox only does storage: it explains changes over time, never removes anything without your review, sends everything to the Trash first, and costs $9.99 once, with no subscription, account or analytics.

How would you describe the primary audience of your product?

DiskFox's answer

Mac owners whose storage keeps running out, especially on 256 GB Macs: people puzzled by "System Data", developers with Xcode, Docker and package caches, and anyone whose app caches quietly grow back.

What's the story behind your product?

DiskFox's answer

I'm Krishan, a solo developer in the UK. My own Mac kept losing 20 GB at a time to "System Data", and nothing could tell me what had changed or why. So I built an app that keeps a history and explains the changes, carefully, without deleting anything behind your back.

Which are the primary technologies used for building your product?

DiskFox's answer

Native Swift and SwiftUI for macOS. Sparkle for updates and Polar for licences. Everything runs on your Mac, with no servers or accounts.

    Don't pay $10 for what you can get for free: https://github.com/RobinNaumann/disko, https://grandperspectiv.sourceforge.net/, https://www.derlien.com/, etc… Otherwise, this is good advice. My cousin, who isn't particularly computer... - Source: Hacker News / 5 months ago
  • Anthropic Cowork feature creates 10GB VM bundle on macOS without warning
    I simply run GrandPerspective (GUI app, https://grandperspectiv.sourceforge.net/), or dust (terminal app, https://github.com/bootandy/dust), to give me an idea of what is going on with disk usage. - Source: Hacker News / 8 months ago
  • Anthropic Cowork feature creates 10GB VM bundle on macOS without warning
    I’d recommend GrandPerspective:[1] it’s really good at displaying this sort of thing, has been around for over two decades, and the developer has managed to keep it to <5MB which is perfect when you’re running very low on space. [1]... - Source: Hacker News / 8 months ago
