CometChat’s Chat SDKs now work offline. Conversations load from the device, messages sent without a connection queue up and survive a restart, and missed changes sync back on reconnect. Off by default, on with one setting at init, with optional encryption for the local cache. Live in our JavaScript, Android, iOS, Flutter, and React Native SDKs.

Could you build this?
No A production offline-capable chat SDK needs distributed-systems work: durable local queues, conflict resolution, sync across many platforms, and encrypted caches. It must be reliable at scale across many customers.
What it would actually take: Building this requires a multi-platform SDK team (JS, iOS, Android, and more) and a backend that handles message ordering, deduplication, and sync semantics. It also needs encryption design, long-term SDK maintenance, and load testing. This is serious infrastructure engineering, not a vibe-coded feature.
