The problem
“Your disk is almost full.” Now what?
The warning comes at the worst time
Mid-export, mid-build, mid-update. You start deleting random things just to get unstuck.
You don't know what's safe
“System Data”, caches, Library folders. Delete the wrong one and something breaks.
Cleaners only know one move: delete
That 40 GB video project or AI model isn't junk. You just don't need it on your Mac today.
Clearbay adds the missing option: move it off your Mac safely, and bring it back with one click.
What you get
More free space. Zero regrets.

Vital Signs
Never get surprised by “disk full” again
A daily free-space history shows how fast your disk fills, “purgeable” and “System Data” explained in plain words, and a menu-bar alert before it's too late.

How it works
Full disk to free space in three steps.
01
Scan
Clearbay measures your Downloads and the folders you grant, such as Home and Applications, in seconds. It never opens your documents.
02
Choose
Remove, Keep or Offload, item by item. Keep is always the default, and Clearbay can suggest a plan using only items its rules allow.
03
Run
Review the whole plan on one screen, like “Remove 14 GB · Offload 23 GB”, then click Run. Every run can be undone.
The real app
Native, calm, made for macOS.
Light and dark mode, full keyboard control, Quick Look previews and VoiceOver labels.
Every item labelled
Offload with a verified copy
Who it's for
Built for Macs that fill up fast.
Developers
Reclaim gigabytes of caches
Xcode DerivedData, Gradle, npm, uv, CocoaPods. Labelled Safe when tools rebuild them on their own.
AI tinkerers
Park models on a drive
Ollama, Hugging Face and LM Studio models are huge. Offload the ones you aren't using this week.
Creators
Archive finished projects
Final Cut libraries, raw footage and photo bursts move to your drive, verified and restorable.
256 GB Macs
Stop juggling space
Auto-Dock keeps Downloads and screenshots off your Mac, and the menu-bar alert warns you early.
Safety first
Nothing moves without your OK.
Clearbay is built so the worst case is “I'll put that back”.
Verified copies
Offload checks file count and total size on the destination before freeing anything. If a step fails, the original stays put.
Trash, never erase
Remove moves items to the Trash, so you can change your mind until you empty it.
One-click restore
Every offloaded item is listed with a Restore button. Undo a whole run in one click.
You review every run
Keep is the default for everything. Nothing happens until you look at the plan and click Run.
Rules, not guesses
Safe, Review and Caution labels come from built-in rules. AI only explains, and never picks items for you.
Off-limits by design
System folders, Keychains, Mail, Messages, the Photos library and .git folders are never touched.
Simple pricing
Pay once. Keep it.

Secure checkout by Stripe. Unlocks the moment you install Clearbay from the Mac App Store, no licence key.
Buy Pro here on clearbay.app (sold by Bisai Technologies, LLC, payments by Stripe, 30-day refunds) or as an in-app purchase in the Mac App Store app (sold by Apple; the App Store shows the price for your country). Either way you sign in once and Pro is yours.
Only if you choose Remove, and then it moves the item to the Trash so you can put it back. Offload copies the item to your drive or cloud, checks the copy, then frees the space. Nothing happens until you review the plan and click Run.
What if my drive is unplugged?
Your offloaded items stay safe on the drive. Clearbay shows which drive holds each item, and you can restore it the next time you connect. Auto-Dock waits too: new files stay on your Mac until the drive is back.
Does it need Full Disk Access?
No. Clearbay comes from the Mac App Store and runs in Apple's sandbox. Downloads works right away; grant your Home or Applications folder with one click each in a standard macOS folder picker.
Is the AI required? Does it see my files?
No and no. Built-in rules set every safety label on any Mac. On Macs with Apple Intelligence, explanations run on-device, so nothing about your files leaves your Mac. You can turn AI off in Settings.
Will my developer tools still work after offloading caches?
Yes. Gradle, npm, uv and Xcode rebuild their caches on their own. If you'd rather not wait, restore the offloaded copy with one click.
Is there a subscription?
No. The free version stays free. Clearbay Pro is a one-time in-app purchase on the Mac App Store.
Which Macs are supported?
macOS 14 Sonoma or later. On-device AI explanations need Apple Intelligence (macOS 26 on a supported Mac); everything else works without it.
