Internet is Optional.
Care is Mandatory.

NidanEHR runs fully offline. Local Kafka queues every transaction. When connectivity returns, sync happens automatically — zero data loss.

📴
Full Offline Operation

All clinical, billing, and laboratory workflows run without internet. Zero workflow disruption during outages or remote deployments.

📦
Local Event Queue

Kafka runs on-premise, storing every transaction as an immutable, ordered event log until synchronization is available.

🔄
Auto-Sync Engine

Intelligent background sync resolves conflicts deterministically and propagates all queued events when connectivity is restored.
