macOS Storage showed 108GB of “System Data” with no drill-down.
Paid disk analyzers work, but they’re usually $10–20 and closed source.
So I built BloomDisk — a free, open-source alternative that runs locally on your Mac.
What you get:
• Sunburst / treemap / list views (click to drill down)
• System Data estimate (closer to macOS Settings)
• Largest files + duplicate finder
• Dev cleanup (Xcode, npm, pip, Homebrew caches)
• 100% local — no cloud, no account, no telemetry
Why I built it:
I wanted DaisyDisk-style visibility without paying for another Mac utility.
Try it:
bash
git clone https://github.com/Nabilhassan12345/BloomDisk.git
cd BloomDisk
npm install && npm start
