What each one is

The product in its own terms, so the numbers below have context.

lsyncd

Watches a local directory tree for changes using filesystem event notifications (inotify or fsevents) and efficiently synchronizes them to a remote target using rsync or SSH, without requiring block-level mirroring or filesystem modifications.

Independently observed

Syncthing

Leader

Syncthing automatically synchronizes files between multiple computers in real-time while encrypting all communication and storing data only on your own devices. It operates without central servers, giving you complete privacy and control over where your data is stored and who can access it.
