Offline-first apps promise instant loading and privacy, but in practice, very few apps get offline support because getting sync right is surprisingly hard.

Local-first apps promise instant loading and privacy but remain uncommon due to synchronization challenges. Building offline-capable applications creates distributed systems where multiple devices modify data independently, requiring solutions for unreliable event ordering and data conflicts. Hybrid Logical Clocks (HLCs) solve ordering issues by combining physical and logical timestamps, while Conflict-Free Replicated Data Types (CRDTs) handle conflicts through strategies like Last-Write-Wins. SQLite serves as an ideal foundation for local-first architectures, enabling reliable offline functionality through message-based synchronization that guarantees eventual consistency across devices.

Why Local-First Apps Haven’t Become Popular?

I keep trying till I find the right solution… Glad that it is not just me who fight this beast! :D

Every time trying to do local first i end up that it’s very hard to support. One thing to sync data with a cloud but there also issue of managing migrations which becomes harder in locale first apps comparing to traditional ones. I feel like I would omit doing it unless it really necessary

Tried to do local first app multiple times, ends up building to cloud based and never implemented local logic
