Are you wondering about the programming language to develop an application? The most common answer for it will be React Native.
To the fact, React Native has managed to gain the title of “Prime Choice” for mobile app development. All in all, React Native is widely being used by the establishments who are trying to make their way to enter the domain of the app.
Nowadays, React Native developers are in a lot of pressure for creating a high-performance application which works in the offline mode and can be scaled as per the requirements. But, there are a lot of prerequisites to develop such apps.
In this writeup, we will be discussing one such important prerequisite that is React Native database. We can call it the backbone of React Native applications. So, let’s dig into the list of the best backend for React Native in 2025.
Wait, before getting deep into the database, it is essential to have a look at the aspects to consider while choosing the React Native DB.
Points To Take Note While Choosing React Native Database
Ease of Use
It is always important that you choose a React Native database that can be integrated with minimal efforts. But, how will you choose the best database? The optimal approach is to hire React Native developers or consultants with experience in app database management.
Concurrency
Once an app gets popular, the work of developers increases and a huge amount of data is to be managed now. A lot of requests will be coming from the users and it is quite tough to serve the correct data to them. Therefore, it is utmost important to know about the concurrency mechanism implemented by the different React Native local database.
Memory Management
When data is not managed in a proper way, the chance of application to get crashed increases. Although, most of the databases typically clear their cache in time intervals which ensures that enough memory is available to run an application perfectly.
Offline Data Synchronization
These days users want their application to work in the offline mode too or when the internet connection is down. Henceforth, it is essential to integrate the database that enables data sync when the user is connected back to the internet.
Data Complexity
It is analyzed that for most of the apps, data is stored either in the form of a JSON structure or key values. This makes it important to choose a database which can handle the complex data structures like objects or full documents.
Best React Native Local DataBase
1. Realm DataBase
An open-source and object-oriented database which works 10 times faster than that of the relational database. In addition to it, the Realm supports complex data types for offline and real-time applications.
You can customize the Realm database for iOS, Android, and Javascript as well. To the fact, this React Native local database has its own search engine and does not require object-related mapping or any key-value stores. The objects stored in the Realm database are enabled to access multiple threads or sources.
Developers choose Realm databases to enhance high performance for the React Native app by handling extensive data. In terms of performance, the Realm has proven to solve the queries better in comparison to SQLite and many other databases. The below-given graph will give you a better understanding of the same.
Overall, Realm database is suitable or we can say the best option for the large-sized application.
Pricing: In a way, the Realm is an open-source platform. But the advanced version will cost you $1750 per month. The pro version comes with Realm studio and many other amazing features for enterprises.

2. Firebase DataBase
We can call Firebase as a Google-owned database with NoSQL. React Native Firebase database will suit best if your app is more into data synchronization and offline updating of data.
Notably, Firebase is capable of handling React Native applications based on MVC. The database is specially developed for collaborative and multi-user apps who have high requirements for data.
The best part here is Firebase comes with performance tracking tools which will help you figure out a bug in your app. It provides you with complete access to remove the data from the Google server at any moment of the time. The evaluation process completed by Firebase is ISO 27001 and SOC1, SOC2, and SOC3.
Pricing: Firebase is free to use up to 1GB, and thereafter you need to pay $25 to store data of around 2.5GB.
Advantages of Firebase
3. SQLite DataBase
SQLite – the most popular and used database engine across the global. This database is built especially for mobile devices. Considering this, SQL database is small, fast, and highly reliable to be integrated with any application.
This React Native DB does not run on any separate server but will write the content directly into the various files. The data is stored by SQLite in the plain text format, which you can even encrypt with SQLite Encryption Extension (SSE).
The extension will encrypt the data, as well as metadata for a, react native application. Here every database file will have their own unique key for the decryption. SSE is licensed software, yet you can buy the source code for $2000.
Pricing: SQLite is a public domain, henceforth free to use. To get the perpetual right to use the source code, you need to pay $6000(one-time fee).
Advantages of SQLite
4. PouchDB DataBase
An open-source Javascript database that will store the data in JSON format. The API here will give you access to the database with just a single call React Native platform. PouchDB enables you to create, update, delete, read and query the object for your API.
PouchDB uses HTTP protocol and JSON, therefore this database is highly compatible with almost every application. It also uses IndexedDB for saving the data to the browser when there is no internet connection.
When the internet connection is back, the data is synced to the backend servers like CounchBD. This react native database is extremely fast with the complex data structures. To secure your data, you can use pouchdb-authentication plugin.
Pricing: PouchDB is free to use, but you are opting for CouchDB, you have to pay for CouchDB cluster. You can easily find all the updates of PouchDB on GitHub.
Advantages of SQLite
5. AsyncStorage Class DataBase
A react-native local database, which lets you store the data in the system storage. AsyncStorage class will let you persist the data between the app reboots. There is no need for any additional deployment here because it has in-built React Native.
The objects are stored in Async Storage(a class), which are considered as a string. All values here need to be deserialized before storing and should be decentralized after retrieving. However, it takes time for the serialization, which, in turn, makes the process slower. If you’re dealing with a large amount of data, it is advisable that you don’t AsyncStorage class.
In terms of security, there is no encryption provided by this react native database. In fact, the database does not offer any sync for the offline thing.
Pricing: It is free to use.
Advantages of AsyncStorage class

6. Watermelon DB
Watermelon DB is developed with an intention to optimize the react native database. It is built on the top of SQLite and offers high performance to react native DB.
The database comes with the capability to scale thousands of records within one minute. According to the official statement of Github, it is optimized for developing complex applications that focus on real-world performance.
Besides, it handles data persistence with slow end devices by being lazy. As a result, you are unable to load any request until it is requested at the first position. Watermelon DB can deal with multithreaded and highly cached async operations.
Advantages of Watermelon DB
Server-Side Databases for React Native App Development
Above all, there are a few react native databases which work for server-side. Here, we have mentioned the three best server-side databases.
1. MYSQL for React Native
A relational database that is based on the SQL. This database supports the multi thread-based allocation of memory, which makes it work faster with complex data. For avoiding server-side vulnerabilities, MYSQL comes with encryption of the data.
The database is designed in a way that it can seamlessly handle a large amount of data. It has a capacity of handling approximately 64 indexes per table and each index contains 1 to 16 columns. Above all, there are a few libraries that make it easy to use SQLite with React Native.
2. MongoDB for React Native
An open-source server-side database that is built to handle the complex application. MongoDB follows a method with a key-value store and JSON to store the data with dynamic schemes.
If you have to deal with huge data, this react native DB will let you modify the schemas without affecting the application in runtime. For a query, MongoDB works with a simple Javascript interface which makes it as simple as passing a Javascript object.
3. Amazon DynamoDB for React Native
