There is no surprise to the fact that React Native has emerged as a major preference for startups and other established enterprises. It is a popular cross-platform mobile app framework that is widely used by developers all across the globe. The recent studies revealed that more than 42% of developers use React Native for building high-performance applications. However, the react native developers feel a lot of pressure in delivering offline-first apps. They sometimes feel it challenging to opt for the right tech stack incorporating the right database for React Native.

In this post, we will provide you with the list of databases that work best for react native app development. Let’s find out the details.


One of the most popular ones on the list is Firebase, which is a Google-owned database that has NoSQL. If you creating an app that is more into offline data synchronization and data updating, then Firebase is the perfect pick for you. It can efficiently manage the MVC-based React Native apps with high data requirements. Not just that it features performance tracking tools that help in accessing the bugs in the apps. Also, it gives complete access to data removal from the Google server as and when required. That makes it pretty amazing!


  • Easy to combine with any app.
  • It helps you fix controls on the file by addressing the users’ roles.
  • Can synchronize the data throughout different platforms.
  • Catches the data on various devices to offer offline access to the users.


An open-source and object-oriented database that operates almost 10 times quicker than the other databases, Realm definitely makes this list. It can support complicated data types for offline and real-time apps. The objects that are preserved in the Realm database can easily be accessed by other threads and sources. Most developers go for Realm database to enhance the performance of React Native apps that is dealing with vast data. Not just that, Realm is considered better in fixing the queries than SQLite and other databases.


  • Comes with a great set of APIs.
  • The synchronization keeps running in the background thus saving the user interaction.
  • It is offline-friendly with Redux offline.


Another one on the list is SQLite. It was initially used to provide users the capacity of making the local storage databases for mobile apps. It requires minimal setup and features extra tools that help in easy management of the data. The SQLite source code is free to use and is in the public domain. While the performance quality is quite debatable, the greater results can be accomplished if you have encountered amazing database development.


  • Allows offline persistence in the app using its storage.
  • Can save the data in the cross-platform database file.


If you are stuck in optimizing the most tricky apps, then WatermelonDB is a great one to go for. It can efficiently scale up to thousands of records in just a few minutes. Not just that, it can handle multithreaded async and highly cached functions with ease. In short, it is built with the purpose of optimizing the React Native database, thus providing excellent performance.


  • It features an offline-first system by synchronizing the engine.
  • Comes with static typing with the flow.
  • When the changes are done in the database, UI gets rendered automatically.
  • Simple data plugins into components.

Final Thoughts

Before you make your final selection, make sure you create a list of your requirements. Stick to those requirements and don’t make any compromise while making the final call for database selection. Don’t forget the success of your app largely relies on the database that you choose. So, choose wisely!
