What it does
Source · target · mode
Keep the source, target, mode and extra arguments in a single profile. Create as many as you like and switch instantly from the sidebar.
Full control
Mirror the target exactly, or only add files. Nothing is deleted unexpectedly, you stay in control.
Set and forget
Enabled profiles run quietly at every login, integrated with your system through a LaunchAgent or login item.
Fast & clean
Sync and copy are called directly. No drives to mount, no virtual disks to create.
GUI → command line
Set up a new cloud connection step by step. SyncDeck builds and runs the underlying engine command for you.
Multilingual interface
Ready in English, Turkish, German, Spanish, Chinese, Japanese, Russian, Dutch and Arabic.
Two modes
engine · sync
Makes the target identical to the source. Files missing from the source are deleted at the target too, for when you want an exact reflection.
engine · copy
Adds files to the target and deletes nothing. The safe choice for more cautious use, no risk of irreversible data loss.
