What are CRDTs and how do they work in smallstack?

CRDTs let multiple users edit the same data offline without conflicts—merges always consistent, no locks needed. smallstack uses them for lists/text, LWW timestamps for scalars.

Is smallstack's local-first good for enterprise apps?

Yes for field teams needing offline reliability—instant reads/writes, real-time sync when online. Skip if you crave strict ACID transactions.

How does SignalDB sync with MongoDB?

Client pulls deltas by timestamp, merges locally, pushes changes async. Server broadcasts via SSE for live updates across peers.
