The problem

Which drive is it on? The only way to know is plugging them in, one by one. Somewhere in that stack is the file you need.

What it does

Auto-scan on mount

Plug in. It catalogs itself.

Connect a drive and Guardian quietly records its contents, folder sizes, capacity and free space. No exports, no sessions to manage.

Offline search and previews

Find a shot without mounting a thing.

Search every cataloged drive at once, then scrub video previews with the drive still on the shelf. R3D, ARW and ProRes previews are generated on your machine, for your formats.

Single-copy exposure

Know what exists in only one place.

Guardian marks footage that lives on exactly one drive. 29.6 of 41.1 TB on this shelf sits in one place, which is a risk you want to see coming.

On your iPhone

Your shelf, in your pocket.

The free iPhone app pairs with Guardian on your Mac and keeps the whole catalog on your phone. Stand at the shelf and know which drive to pick up. It syncs over your own Wi-Fi, and nothing goes through the internet.

Guardian for iPhone's shelf: three drives with their free space, file counts and when each was last cataloged.

Local-only by design

Nothing leaves your Mac.

The catalog is a file on your machine. No cloud, no account, no telemetry. Client footage stays where it belongs.

FAQ

Can't Spotlight or Finder do this?
No. macOS doesn't index drives that aren't connected. Guardian keeps its own catalog, so search and previews work with the drive in a drawer.
Is Guardian a backup tool?
No. Guardian tells you what's on every drive and what exists in only one place, so you can see where you're exposed. Backing up stays your call.
Does my footage leave my Mac?
Never. The catalog lives on your machine. No cloud, no account, no telemetry.
What does it cost?
Free to download, and it catalogs your first drive free. One payment unlocks unlimited drives, yours for good. No subscription, no renewal. The price is set for your country and shown at checkout.
Is there an iPhone app?
Yes, and it is free. Guardian for iPhone pairs with Guardian on your Mac over your own Wi-Fi and keeps the catalog on your phone, so you can search every drive with none of them near you. It reads the catalog only: no files, no account.
Which formats get previews?
R3D, ARW, ProRes and everything macOS can decode. Previews are generated on your machine, tuned for footage drives.

Every drive, accounted for.

One drive free. One payment unlocks the shelf.
