What is 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.

Is lsyncd open source?

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for lsyncd, not the verdict.
