I built a native GUI for direct server-to-server transfers (FTP/SFTP) because rclone CLI wasn't visual enough for me.

The author built a native GUI app called SyncShuttle for direct server-to-server file transfers via FTP/SFTP, using rclone as the underlying engine. It features a split-pane interface for dragging folders between servers and a compare-only mode, addressing the pain of manually downloading and re-uploading large files during site migrations. The app is available as a paid one-time license for macOS and Windows.
