Which is exactly why I said this problem is better solved by your own custom sync engine which when scoped to your own problem is not as hard to build as you think the most simpler and effective version is just a change_log and replaying or occasional full sync.

My own app uses something like this and I have yet to encounter any issue whereas I did initially look into using electricsql , zero sync , instantdb , triplit but the amount of lock-in or DSL was not my cup of tea and most of these are now doing "AI Agents" marketing instead of their core original problem which further erodes any trust.
