Realm vs SQLite
Developers should learn Realm when building mobile apps that require high-performance local data storage with real-time updates, such as chat applications, collaborative tools, or offline-capable apps meets use sqlite for embedded applications, mobile apps, or desktop software where a lightweight, file-based database without a separate server process is needed—it excels in scenarios like local caching or prototyping. Here's our take.

Realm
Nice PickDevelopers should learn Realm when building mobile apps that require high-performance local data storage with real-time updates, such as chat applications, collaborative tools, or offline-capable apps
Pros
- +It's particularly useful for scenarios where complex object relationships need to be managed efficiently without manual SQL queries, and when seamless synchronization with a backend (via Realm Sync) is needed for multi-user experiences
- +Related to: react-native, flutter
Cons
- -Specific tradeoffs depend on your use case
SQLite
Use SQLite for embedded applications, mobile apps, or desktop software where a lightweight, file-based database without a separate server process is needed—it excels in scenarios like local caching or prototyping
Pros
- +Avoid it for high-concurrency web applications with many simultaneous writes, as it uses file-level locking that can cause bottlenecks
- +Related to: sql
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Realm if: You want it's particularly useful for scenarios where complex object relationships need to be managed efficiently without manual sql queries, and when seamless synchronization with a backend (via realm sync) is needed for multi-user experiences and can live with specific tradeoffs depend on your use case.
Use SQLite if: You prioritize avoid it for high-concurrency web applications with many simultaneous writes, as it uses file-level locking that can cause bottlenecks over what Realm offers.
