This looks very compelling from a DX perspective — especially the “local JSON that just syncs” mental model.
Just curious - What conflict resolution model are you using (CRDTs / OT / something else), and how deterministic is it under concurrent offline edits?
I should have written a disclaimer - I am not a part of this project nor am I affiliated with them in any way. It just looked great from the DX perspective, but I didnt stumble upon any mention of conflict resolution.
