Keep your local folders perfectly in sync with the cloud — automatically, in the background, with per-folder control over timing and conflict resolution. Follows your system light or dark theme.
Simple to set up, powerful enough to handle exactly how you want your files synced.
Local changes upload immediately. Remote changes are pulled on your chosen interval — per folder, globally, or both. No one-way limitations.
Save a file and it's in the cloud within seconds — no manual syncing, no waiting. CloudSync watches your folders and uploads changes as soon as they happen.
Each sync folder can override the global interval and conflict strategy independently. Or inherit the global defaults — your call.
Connect Google Drive, Dropbox, and S3-compatible storage simultaneously. Each folder maps independently to whichever provider you choose.
Looks and feels like a native Linux app. Follows your system light or dark theme. Lives quietly in the system tray — close the window and it keeps syncing in the background.
One-click presets for Amazon S3, Backblaze B2, and Cloudflare R2. Use the visual Browse button to navigate buckets and subfolders in the setup wizard.
A step-by-step wizard walks you through connecting your cloud account and choosing your first sync folder. Sign in with your Google or Dropbox account — no technical setup needed.
Get notified when a sync completes or if something needs your attention. An in-app activity log keeps a full history of everything CloudSync has done.
Turn on autostart in Preferences and CloudSync launches silently with your desktop — your folders are already in sync before you open the app.
Choose how CloudSync handles files edited in two places. Set a global strategy and override it per folder.
Default: Keep Both Copies — the safest option. No data is ever silently lost.
Check the cloud for new changes every 30 seconds, 1 minute, 5 minutes, or 15 minutes — your choice, globally or per folder.
Files you save locally are uploaded within seconds — no waiting for the next scheduled check.
Need it now? Sync any individual folder instantly with one click from the main window.
Your cloud account logins are stored only on your machine and are never transmitted anywhere.
CloudSync is distributed as a Flatpak. Purchase a subscription to receive your download link and license key.
Purchase a subscription below. You'll receive a download link and license key by email immediately after checkout.
Open the downloaded file and follow the on-screen instructions to install. CloudSync appears in your application menu when done.
Launch CloudSync, enter your license key, and the setup wizard walks you through connecting your cloud accounts and choosing which folders to sync.
One flat subscription. Unlimited folders, unlimited providers, automatic updates included.
Cancel any time. The app keeps working — you just won't receive future updates.
CloudSync keeps running — your sync folders, accounts, and settings are all preserved. You just won't receive new updates until you renew.
No. Your account credentials are stored only on your own computer and are never sent to SeraVault's servers.
You can connect one account per provider type (one Google Drive, one Dropbox, etc.), but you can connect all five providers simultaneously. Each sync folder maps independently to whichever account you choose.
CloudSync works on any Linux distribution that supports Flatpak — including Ubuntu, Fedora, Pop!_OS, Linux Mint, Arch, and more.
CloudSync is an independent app that syncs local folders with cloud storage providers. It does not provide encryption, secure storage, or any of the security features of the SeraVault vault app — it simply keeps your local folders in sync with your cloud accounts. It is published under the SeraVault brand but operates entirely separately.
Set it up once. CloudSync handles the rest — automatically, in the background, on your terms.
