As answered by people managing BleachBit and DiskInsight.
DiskInsight's answer:
DiskInsight is fully local: there is no account, no cloud and no telemetry, and it is free to scan. Instead of a single treemap like most analyzers, it renders any drive in nine visualizers (treemap, sunburst, flame graph, bubbles, mind map, age map, top sizes, list and folders) with instant search. Cleanup is a one-time Pro unlock rather than a subscription, and it includes a developer cache cleaner for Xcode DerivedData, npm, CocoaPods and Gradle.
DiskInsight's answer:
Solo developers and power users on macOS: engineers whose dev caches (Xcode, npm, CocoaPods, Gradle) quietly eat tens of GB, designers and creative pros working with large media, and anyone who wants to understand and reclaim disk space privately without a subscription or an account.
DiskInsight's answer:
Native macOS app built in Swift/SwiftUI (fully on-device, no network calls), with a static Astro marketing site and a license-check / copies store backed by SQLite.
DiskInsight's answer:
Because the hard part — understanding where your space went — is free forever, and you only pay once if you want cleanup. Unlike subscription cleaners, DiskInsight explains your storage instead of aggressively deleting it, keeps every byte on your Mac, and adds developer-focused features (dev cache cleaning, content-hash duplicates, a real uninstaller) that general Mac cleaners do not.
DiskInsight's answer:
I kept getting the macOS 'startup disk almost full' warning and none of the existing tools told me why space was gone — they just offered to delete things. I built DiskInsight as a 100% local analyzer that explains every byte first, then added a one-time Pro unlock for cleanup, so it stays a tool I would actually want to use myself.
