Custom Sync Logic vs Realm Sync

Developers should learn and use custom sync logic when building applications that require precise control over data synchronization, such as real-time collaborative tools, offline-first mobile apps, or systems with complex business rules that standard sync frameworks cannot accommodate meets developers should use realm sync when building applications that require real-time data updates across multiple devices, such as collaborative editing tools, chat apps, or iot dashboards. Here's our take.

Custom Sync Logic

Nice Pick

Developers should learn and use custom sync logic when building applications that require precise control over data synchronization, such as real-time collaborative tools, offline-first mobile apps, or systems with complex business rules that standard sync frameworks cannot accommodate

Pros

• It is essential for handling edge cases like conflict resolution, network latency, and partial updates, ensuring data integrity and user experience in distributed environments
• Related to: distributed-systems, data-consistency

Cons

• Specific tradeoffs depend on your use case

Realm Sync

Developers should use Realm Sync when building applications that require real-time data updates across multiple devices, such as collaborative editing tools, chat apps, or IoT dashboards

Pros

• It is particularly valuable for mobile-first or offline-first applications where users need to work without a constant internet connection, as it provides automatic conflict resolution and efficient data synchronization upon reconnection
• Related to: realm-database, mongodb-realm

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Custom Sync Logic is a concept while Realm Sync is a platform. We picked Custom Sync Logic based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Custom Sync Logic wins

Based on overall popularity. Custom Sync Logic is more widely used, but Realm Sync excels in its own space.
