The hogs hiding in plain sight.
Old iOS backups, node_modules, Xcode DerivedData, Docker volumes, leftover Mail downloads. Delve surfaces the space eaters that never show up in About This Mac.
A clearer Mac starts here
Delve turns your drive into one clear, interactive map. See what’s large, preview it, and reclaim space with confidence.
From full drive to free space
Old iOS backups, node_modules, Xcode DerivedData, Docker volumes, leftover Mail downloads. Delve surfaces the space eaters that never show up in About This Mac.
Quick Look any file, reveal it in Finder, or inspect its folder. Nothing moves until you choose.
Stage what you don’t want into the Collector as you browse, from the treemap, the sunburst, or the file list, and watch the reclaimable total climb. Send the batch to the Trash in one reviewed action, where a wrong call is still one undo away. Delve never deletes on its own, and nothing leaves your Mac.
A 1 TB drive with a few million files maps in under 90 seconds on a base M2, reading a whole folder of metadata per system call instead of one file at a time.
The treemap for size at a glance, the sunburst for how
deep a folder really goes. Scroll to zoom either one
and it stays anchored under your pointer, then
step back through where you've been. Export any map as a
poster with ⌘⇧E.
Drag any folder onto the window and let go. No file picker, no dialog. Or start from Places in the sidebar for the usual suspects: Downloads, Documents, the Library caches.
Internal SSDs, external disks, Time Machine volumes, network shares, even iCloud Drive. If Finder can see it, Delve can map it.
Light or dark, Delve follows the system, treemap included, not just the window chrome. Pin it either way in Settings if you'd rather choose.
No subscription, no account, no telemetry you didn't opt into. Pay $4.99 once and it's yours, and the scan never leaves your machine.
A number you can trust
macOS can make one file look much larger than the room it really uses. Delve handles that complexity for you. When it says deleting something will free 12 GB, that is the number that matters.
/Library/Developer/Xcode/iOS DeviceSupport
You'd save 12.1 GB deleting this, not 87. The rest are APFS clones sharing the same blocks.
~/iCloud Drive/Documents · dataless stubs
Cloud stubs detected and tagged with a cloud glyph. We never accidentally materialize a file just to read its size.
The long form on hit-testing, cushion shading, and the bulk-stat trick lives in the architecture post.
Private by design
Every scan happens on your Mac. File names, paths, previews, and contents are never uploaded. There is no account to create and no cloud library of your files.
Delve asks for Full Disk Access only so it can show you the complete picture. That permission stays between you and your Mac.
Simple, honest pricing
One app, every feature, one payment. No tiers, account, renewal, or surprise at checkout.
Delve for Mac
$4.99 one time
$4.99, paid once. There's a 14-day free trial with every feature unlocked and no card needed to start. After that, one payment unlocks Delve for good, deletion included, with free updates and no subscription. The full breakdown is on the pricing page.
No. Delve needs macOS 26 and Apple Silicon. On an Intel Mac or older macOS, GrandPerspective and OmniDiskSweeper are free alternatives that still run.
No, on purpose. The App Store requires sandboxing, and a sandboxed app can't see most of your disk, which defeats the point of a disk scanner. Delve is a notarized direct download with signed auto-updates: the same security level, without the limitation.
No. Delve needs Full Disk Access to do its job, but nothing leaves your machine. There's no server. Optional anonymous analytics cover version, OS, and aggregate feature usage only, never a file name, path, or extension.
Delve is $4.99 with a 14-day free trial and includes deletion. It draws both a treemap and a sunburst, and shows on-disk versus logical size with APFS clones deduped. DaisyDisk is $9.99 with deletion behind the purchase, and runs on Intel and older macOS. The full Delve vs DaisyDisk breakdown is here.
