SeraVault CloudSync — Two-Way Cloud Sync for Linux

CloudSync keeps users' folders in sync with various cloud storage services including Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, Cloudflare R2, Wasabi, and more. It is a native Flatpak Linux app that runs quietly in the background, watching local folders and keeping them up to date with the connected cloud accounts. The app supports two-way sync, allowing changes from both the local machine and the cloud to be reflected in both locations. Users can control the sync interval for each folder, choosing from intervals such as 30 seconds, 1 minute, 5 minutes, or 15 minutes, or setting a global default. The app features smart conflict resolution, allowing users to decide how to handle files changed in both locations. CloudSync stores cloud account logins only on the user's computer and never sends them elsewhere. The setup process is guided by a step-by-step wizard that connects cloud accounts and chooses sync folders without requiring technical setup. CloudSync is designed for Linux desktop users who need reliable cloud backup. It is available as a Flatpak bundle, with automatic updates available through the Flatpak ecosystem, supporting distributions such as Ubuntu, Fedora, Pop!_OS, Linux Mint, and Arch Linux.
