What is local-first sync?

The local database is the source of truth; the server catches up.

Local-first sync inverts the usual web app: reads and writes hit the local database instantly, and changes replicate to the server asynchronously. Every user keeps a working copy; sync reconciles them.

Technicians in a plant with intermittent signal work against the local store all shift; queued changes push when connectivity returns — in order, retried safely, without losing a single job.
