Your files. Always up to date.

CloudSync watches your local folders and keeps them in perfect sync with Google Drive, Dropbox, Amazon S3, Backblaze B2, or Cloudflare R2 — automatically, in the background.

What makes it different

Set it up once. Forget about it.

Two-way sync

Save a file and it's in the cloud within seconds. Changes from the cloud download automatically on your chosen schedule.

Per-folder control

Each folder can have its own sync interval and conflict strategy. Or inherit the global defaults — your call.

Smart conflict resolution

When the same file changes in two places, you decide: keep both copies, keep yours, or keep the cloud version.

Lives in your tray

Close the window and CloudSync keeps running quietly in the system tray. Turn on autostart and it's ready before you even open the app.

No command line needed

A step-by-step setup wizard walks you through connecting your accounts and choosing your first sync folder.

Your credentials stay on your machine

Cloud account logins are stored only on your computer and are never sent anywhere else.

How it works

Up and running in three steps.

  1. Download & install

    Install CloudSync from Flathub — see the installation instructions below.

  2. Connect your cloud account

    The setup wizard guides you through signing in and picking your first folder to sync — no technical setup required.

  3. Walk away

    CloudSync runs in the background. Your files are always where you need them.

FAQ

Quick answers

Which Linux distributions are supported?

Any distribution that supports Flatpak — Ubuntu, Fedora, Pop!_OS, Linux Mint, Arch, and more.

What's the difference between the free tier and a subscription?

The free tier is permanently available and lets you sync one cloud provider and one folder. A subscription removes those limits and adds automatic updates.

How do I activate my subscription?

Open Preferences → Subscription, enter the email you subscribed with, and click Sign In. The app verifies and unlocks everything right away.

What happens if my subscription lapses?

CloudSync keeps running with all your existing folders and accounts intact. You just won't receive new updates until you renew.

Ready to stop moving files by hand?

Upgrade to CloudSync Pro.
