DaisyDisk alternative: is a sunburst chart enough?

A sunburst chart is enough if the only question you have is "where did my space go" — DaisyDisk answers that better than almost anything else on the Mac, for $9.99, once. It stops being enough the moment the real question is "what's actually safe to delete," "do I have duplicate photos eating 40 GB," or "how do I remove an app and everything it left behind" — DaisyDisk was built, on purpose, to not answer any of those. Here's what it does well as of July 2026, the gaps that send people looking for a DaisyDisk alternative, three free tools that cover the mapping job for nothing, and where SwoopByte Disk fits for what DaisyDisk skips.

What DaisyDisk gets right

DaisyDisk earned its reputation the slow way — over a decade of independent Mac reviewers recommending it unprompted, not through content marketing it runs itself; its own blog is release notes, not an SEO engine. Deserved.

The sunburst view is still the clearest way to see where a drive's space went: concentric rings, click to zoom into any folder, every wedge's size mapping directly to what it represents. DaisyDisk's own materials claim a full scan in around 15 seconds against several minutes through Finder — DaisyDisk's number, not one we've verified, but the fast, responsive feel is consistently the first thing reviewers praise.

The Collector is genuinely good interaction design: drag files from anywhere in the scan into it before committing to one delete, Quick Look a spacebar away to check what something actually is first. Real guardrails too — it refuses to let you drag /System, /Library, or your own home folder into the Collector, scans only file names and sizes, never content, never sending anything off your Mac, a privacy stance SwoopByte's own apps share.

It also detects the "hidden" and "purgeable" space that sits outside what Finder can see at all on an APFS disk — mostly local Time Machine snapshots, plus caches, sleep images, and swap files — and lets you reclaim it in one drag, sometimes recovering tens of gigabytes Finder never accounted for.

Price, version, and the free trial's real limits, as of July 2026

DaisyDisk is $9.99, one time, direct from daisydiskapp.com or through the Mac App Store — no subscription. A direct-purchase license covers up to five personal Macs, with a 30-day money-back guarantee. Current release: 4.34.2, last updated July 10, 2026, running on macOS 10.13 (High Sierra) and later — Intel Macs included, not just Apple Silicon.

A free trial exists only through the direct download; the Mac App Store edition has no trial, because Apple's store mechanics don't support one the way DaisyDisk's direct license does. No time limit on the trial — scan, browse the full sunburst, Quick Look every file for as long as you want. Locked until you pay: deleting anything, scanning cloud-storage folders, admin/super-user scanning, revealing a file in Finder, and periodic reminders to buy (the paid version never shows them). Admin scan mode — seeing restricted system folders and other users' folders with your admin password, the way sudo does — exists only in the standalone version; the Mac App Store edition can't do it at all, even after purchase, because of sandboxing rules.

What DaisyDisk was built, on purpose, not to do

DaisyDisk's own site is explicit that it isn't a "cleaner app" — it calls automated cache-and-temp-file deletion something Apple itself doesn't recommend, and its philosophy is that you decide what goes. Real, defensible position, and it also means the scope is narrower than a lot of people expect from a $9.99 utility.

• No duplicate-file finder, in this version or any past one we found. Two copies of your photo library show up as two separate blobs of space, not a flagged duplicate.
• No app uninstaller. DaisyDisk shows an app's size; it doesn't touch the Application Support files, caches, or LaunchAgents a Trash-drag leaves behind — the same problem we cover in detail here, and exactly what SwoopByte Uninstaller is built for.
• No named breakdown of "System Data." DaisyDisk detects "purgeable space" — mostly local Time Machine snapshots plus caches, sleep images, and swap files — as one macro-level block you drag into the Collector as a whole. It doesn't split that into "Time Machine snapshots: 12 GB, Docker.raw: 8 GB, an old iPhone backup: 4 GB" the way a plain-language breakdown would; for that granularity you're back to clicking through the real folder tree and figuring out what each path is yourself.
• No scheduled or background scans — every scan is something you start on purpose.
• Deleting is permanent, not reversible. DaisyDisk's own manual states plainly that clicking Delete on the Collector removes files for good, not to the Trash, with a 5-second window to hit Cancel first. Disclosed, not a bug — but it matters if what you actually want is a Trash-level undo net.

Three free tools that already do the mapping job

If the only job is seeing where your space went, you don't have to spend anything.

GrandPerspective is the closest like-for-like swap: open source, actively maintained (version 3.7.2 as of mid-2026, native on Apple Silicon), drawing the same size-as-area idea as a treemap of rectangles instead of rings. Deletion is off by default — a Preferences toggle turns it on — and once enabled, it moves files to the Trash rather than deleting outright, the opposite of DaisyDisk's default.

OmniDiskSweeper, from the Omni Group, skips the visual entirely: a plain list of folders and files sorted largest to smallest, color-coded, with a button to Trash or open whatever you select. Old design — it first shipped for OS X Tiger — still getting small updates as recently as September 2025. If a chart is decoration to you, this beats both of the others for gone-in-two-clicks.

Before any of them: macOS's own Storage pane (System Settings → General → Storage) already shows category totals plus three one-click fixes — Store in iCloud, Optimize Storage, Empty Trash Automatically. For a lot of "my disk feels full" complaints, that's the whole fix, for nothing, with nothing to install.

Where SwoopByte Disk fits, and the trade-off, honestly

SwoopByte Disk hasn't shipped yet. The product page takes a waitlist email today, not a download — the honest state of it as of this writing.

The plan for the free tier: the swoop (the scan), a Space Map ring view paired with a ranked list, largest files and folders, a category breakdown, a free-space verdict with an APFS purgeable-space estimate, the entire System Data breakdown — Time Machine local snapshots, Docker.raw, stale iOS backups, app caches and logs, each named with its own real size instead of lumped into one block — duplicate detection with a total-wasted-bytes number, and a one-click clean of user caches, logs, and Trash. The direct answer to the gap above: DaisyDisk detects purgeable space as one thing you can purge; SwoopByte Disk's plan is to name what's actually inside it.

Pro is a one-time $14.99, not a subscription, planned for the reclaim actions themselves — releasing Time Machine snapshots, batch dev-cache cleanup, actually removing duplicates (a group always keeps at least one copy) — plus scan history with a storage diff, scheduled auto-swoops, and an exportable report. Every removal goes to the Trash, with exactly one disclosed exception: releasing Time Machine local snapshots is permanent, lives in its own confirmation sheet, says so plainly, and never touches the actual backup disk. One irreversible action, named up front — not five, buried in fine print.

The trade-off runs the other way too. DaisyDisk works on macOS 10.13 and later, Intel Macs included — nearly a decade of Mac hardware. SwoopByte Disk is planned for Apple Silicon Macs on macOS 14 or later only, a deliberate scope decision, not a temporary gap. On an Intel Mac, or anything older than Sonoma, DaisyDisk or GrandPerspective are the answer, not SwoopByte Disk, no matter what it ships with.

Want the clearest view of where space went and you're fine with permanent deletes: buy DaisyDisk. Want the same idea for nothing, open source, deletes to Trash: GrandPerspective. Just want the biggest files gone in two clicks, no chart: OmniDiskSweeper. Haven't tried anything yet: start with macOS's own Storage pane before spending a cent. Want a named System Data breakdown, duplicate detection with a running total, and dev-cache cleanup, on an Apple Silicon Mac, and you don't mind waiting: join the SwoopByte Disk waitlist. Free when it ships, reclaim actions behind a one-time $14.99.

FAQ

Is DaisyDisk worth $9.99 in 2026?

Yes, for the one job it does — the sunburst view and Collector workflow are still genuinely excellent for seeing where space went. It's a weaker $9.99 if you expected it to find duplicates, uninstall apps, or flag what's safe to remove, because it deliberately does none of those.

Is there a completely free alternative to DaisyDisk?

GrandPerspective is the closest match — free and open source (SourceForge or GitHub), or $2.99 on the Mac App Store — with a treemap view and Trash-based deletion instead of permanent. OmniDiskSweeper (free, Omni Group) skips the visual for a sorted list, and macOS's own Storage settings pane covers a lot of "my disk feels full" complaints for nothing.

Does DaisyDisk delete files permanently, or send them to the Trash?

Permanently, by design. DaisyDisk's own manual states that clicking Delete on the Collector removes files for good rather than moving them to the Trash, with a 5-second window to cancel first.

Can DaisyDisk find duplicate files?

No — it has never had a duplicate-file finder. Two copies of the same folder show up as two separate blobs of space, not a flagged duplicate.

Does DaisyDisk work on Intel Macs?

Yes. It requires macOS 10.13 or later and runs on Intel and Apple Silicon alike — broader hardware support than SwoopByte Disk, which is planned for Apple Silicon on macOS 14 or later only.

What's the real difference between DaisyDisk and SwoopByte Disk?

DaisyDisk is a visualizer you can buy today for $9.99. SwoopByte Disk is a free, Apple-Silicon-only tool still on a waitlist, planned to add a named System Data breakdown, duplicate detection with a wasted-space total, and Trash-based safety by default, with reclaim actions behind a one-time $14.99 Pro upgrade.
