Firebase Realtime Database vs Realm

Developers should use Firebase Realtime Database when building applications that need real-time data synchronization, such as multiplayer games, collaborative tools, or live tracking apps, as it handles data updates instantly across all devices meets 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. Here's our take.

Firebase Realtime Database

Nice Pick

Developers should use Firebase Realtime Database when building applications that need real-time data synchronization, such as multiplayer games, collaborative tools, or live tracking apps, as it handles data updates instantly across all devices

Pros

  • +It's particularly useful for rapid prototyping and small to medium-sized projects due to its ease of setup and serverless nature, reducing backend development overhead
  • +Related to: firebase, firestore

Cons

  • -Specific tradeoffs depend on your use case

Realm

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

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

The Verdict

Use Firebase Realtime Database if: You want it's particularly useful for rapid prototyping and small to medium-sized projects due to its ease of setup and serverless nature, reducing backend development overhead and can live with specific tradeoffs depend on your use case.

Use Realm if: You prioritize 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 over what Firebase Realtime Database offers.
