A home NAS instead of Google Drive or Dropbox

Off The Cloud is free, open-source software that turns a Raspberry Pi 5 with two USB drives into your family's own file storage: a NAS that keeps folders on your computers in sync, backs up your phones and shares files with a link, with no storage plan to pay for every month. The same device is your family's private social network and photo library.

What you keep from a cloud drive

  • Folders in sync. The Mac, Windows and Linux apps keep the folders you choose in two-way sync with the device, or back them up one way, in the background.
  • Your files on your phone. Browse, open, upload and share them from the iPhone and Android apps, or from any browser in the web app.
  • Share links. Send files as a link that expires: whoever has it downloads them as a ZIP, with no account.
  • Nothing lost by mistake. Make a folder upload-only and nothing in it can be deleted, from any app; a file uploaded again under the same name keeps its earlier version.
  • Space for everyone. Each person in the family gets their own account, with their files encrypted under their own password.
  • Faster at home. At home the apps talk to the device over your own network, so big folders sync at Wi-Fi speed instead of your internet connection's upload speed.

What changes when your files come home

  • You buy the hardware once. A Raspberry Pi 5 and two USB drives, mirrored so that each keeps a full copy. Your space is what one drive holds; when it fills up, you swap in bigger drives, one at a time, without stopping.
  • A full backup is easy. The mirror protects you from a drive failing; for a copy kept somewhere else, take one drive out and put a new one in: the device fills the new one, and the one you took out is your backup.
  • Away from home, through the bridge. Your apps reach the device through our relay (free for two years, then €9.99 + VAT a year) or Tailscale Funnel, with no ports to open on your router, or through your own VPN.
  • More than a drive. The same device backs up every phone in the family in full resolution, keeps a photo library you can search, and runs your family's private social network.

Which one should you choose?

  • Off The Cloud if you want your family's files at home, with no monthly plan, on a device that's easy to set up and also backs up your photos and runs your private social network.
  • Google Drive if you live in Google's apps and edit documents together in the browser; it has no Linux app, and its space is shared with Gmail and Google Photos.
  • Dropbox if you want the most familiar sync, Linux included, and don't mind a monthly plan; passwords and expiry dates on links need Essentials or a business plan.
  • iCloud Drive if everyone in your family uses Apple devices: it's built in, with nothing to set up.
  • Proton Drive if you want storage from a privacy-focused cloud company, with open-source apps; there's no Linux app yet.
  • pCloud or MEGA if you'd rather avoid a monthly fee or want plenty of free space: pCloud sells lifetime plans, and MEGA gives 20 GB free.
  • A Synology NAS if you want a traditional NAS, with network drives for your computers and many apps, and don't mind choosing its drives and setting it up.
  • Nextcloud if you already run a server and want calendar, contacts and office apps too: it's free and open source, but installing it, reaching it from outside and backing it up are up to you.

Moving your files over

From Google Drive: download everything with Google Takeout, which can turn Google Docs, Sheets and Slides into ordinary files, such as OpenDocument or PDF. Unzip it on a computer and add that folder to the Mac, Windows or Linux app.

From Dropbox, Proton Drive, pCloud and the like: if the service's app keeps a folder on your computer, make sure every file in it is downloaded, not online-only, then add that folder to the Mac, Windows or Linux app: every file goes to your device. Otherwise, download your files from the service's website first.

From iCloud Drive: on a Mac, copy the files into a folder of your own, outside iCloud Drive, and add that folder to the Mac app.

FAQ

Questions people actually ask

Can I open my files from my computer's file manager?

Yes, through the sync app: the folders you add are ordinary folders on your computer, kept in sync with the device. What there isn't is a network drive (SMB) that opens the device's own storage directly, as a traditional NAS does.

Are my files private?

Yes. Your files are stored encrypted on the device's drives, with a key only your password unlocks, and the password itself is never stored on it. Each person in the family has their own account and key, and nothing is used for ads or to train AI.

What happens if a drive fails?

Nothing is lost: each of the two drives holds a full copy. The device carries on with the other one and tells you which to replace; put a new drive in its place and it copies everything back by itself.

How much space do I get?

As much as one of your two drives holds, since each keeps a full copy. To grow it, swap the drives for bigger ones, one at a time: the device copies everything onto each new drive, then grows by itself, without stopping.
