React Native Development has arisen as a major preference of establishments and startups seeking a mode for entering the app domain cost-effectively and time-efficiently. It is the second most famous cross-platform mobile framework used by developers globally, as per a 2021 developer survey.

According to a survey, 38% of software developers employed React Native in 2021.

A React Native Developer is under great pressure for delivering a high-performing, offline-first app that can be scaled anytime. Therefore, sometimes it becomes hard for developers to opt for the relevant technology stack incorporating the correct database for React Native.

In this blog, I have composed a list of databases for react native app development. They might match your requirements like scaling easily with your user base or supporting offline development capacities.

Best Local Databases for React Native App Development


The Realm is an object-oriented and open-source database that works 10 times quicker than that of the relational database. Furthermore, it supports complicated data types for real-time and offline apps. It doesn’t require any key-value stores or object-related mapping and it has its own search engine. The objects maintained in the Realm database are allowed for accessing many sources or threads.

Developers opt for a Realm database to increase the performance of a React Native application by dealing with vast data. Being a high-performing database, Realm has proven to fix the queries better in contrast to SQLite and other databases. All in all, this database is preferable and the best choice for large-sized apps.

Although Realm is an open-source platform, its advanced version will cost you $1750 monthly. Its pro version features Realm Studio and a few other great features for enterprises.


Firebase is a Google-owned database having NoSQL. If your application is more into offline data updating and data synchronization, Firebase is best for you. Firebase can extensively manage MVC-based React Native apps that have high data requirements.

Moreover, Firebase promotes performance tracking tools that will help you assess a bug in your application. It provides you full access to data removal from the Google server whenever required.

The assessment process done by Firebase is ISO 27001 and SOC1, SOC2, and SOC3. This database is free for using up to 1GB and then you have to pay $25 for storing around 2.5GB of data.


This was initially built to offer users the capacity of making local storage databases for mobile apps. In the name, ‘Lite’ stands for the database’s lightweight, which needs an insignificant setup. It carries out maximum SQL policies with extra tools that help you manage the data easily.

Although its performance quality is arguable, greater results can be achieved for people who have encountered amazing database development. SQLite source code is free for everybody to utilize for any reason and it is in the public domain.


PouchDB is an open-source JavaScript database. It saves data in JSON format and enables all CRUD (Create, Read, Update, Delete) functions to be queried and mutated using a simple JS API.

It allows apps to store data locally even while offline and then sync it with compatible servers and CouchDB when the app is again online, keeping all user data synchronized regardless of where they sign in next. As a dependency, PouchDB is light in weight.

It helps secure data easily for a React Native app. It has an in-built authentication system for React Native and it gives features like password storing in the harsh form with the PBKDF2 crypto algorithm for protecting encrypted keys from degraded attacks.

Async Storage

It’s a local storage framework that enables developers to collect data locally and retrieve it between reboots of an application. This database features React Native in-built; hence, you can utilize it without any more deployment.

Even after you have shut the device or app, Async Storage comes in handy when you require to save the data the app has to use.


This is made with the purpose to optimise the React Native database. It is developed on top of SQLite and delivers excellent performance to React Native Database. WatermelonDB has the ability to scale thousands of records within a minute.

As per Github’s official statement, it is optimized for making tricky apps that focus on real-world performance.

By being lazy, it controls data persistence with low-end devices. And as an outcome, you cannot load any request if it is not requested at first. Moreover, it can handle highly cached and multithreaded async purposes.


Vasern is one of the most lightweight, open-source, and quick databases for developing React Native apps. The Vasern API is used not only for local data storage but also for syncing and cloud storage across the app users. Its structures and design got inspiration from diverse open-source databases.

Final Thoughts
