List of the Top 3 Offline-First Databases for SQLite in 2025

RxDB is a NoSQL database crafted for a local-first approach, making it particularly ideal for modern web and mobile applications. It enables offline-first functionality by storing data directly on the client side using a variety of storage engines such as IndexedDB, OPFS, and SQLite. With its real-time reactivity, RxDB empowers developers to track changes in documents, fields, or queries, allowing UI components to display data updates immediately. Its versatile replication engine supports synchronization with numerous backends and bespoke endpoints, which enhances its adaptability for different scenarios. Moreover, RxDB integrates seamlessly with various frameworks and environments, further boosting its practicality. Among its core features are field-level encryption, schema validation, conflict resolution capabilities, options for backup and restoration, along with support for attachments and CRDTs. By reducing server load and facilitating quick local queries, RxDB significantly enhances performance and scalability, positioning it as an excellent choice for applications requiring real-time updates, offline capabilities, and consistency across platforms. Furthermore, the innovative design of RxDB equips developers with the tools necessary to create dynamic and responsive applications that can efficiently handle user interactions in real-time.

WatermelonDB is an advanced reactive database framework specifically designed for creating powerful React and React Native applications that can scale efficiently from hundreds to tens of thousands of records while ensuring rapid performance. It ensures that applications launch instantly, regardless of the data volume, employs lazy loading to retrieve data only as needed, and includes offline-first features alongside synchronization capabilities with custom backend systems. This framework is inherently multiplatform, being particularly optimized for React, which simplifies data integration into components, and it is also framework-agnostic, allowing developers to leverage its JavaScript API across various UI frameworks. Built upon a robust SQLite foundation, WatermelonDB provides static typing support through Flow or TypeScript, while also offering optional reactivity via an RxJS API. It adeptly addresses performance issues in complex applications by deferring data loading until it is explicitly requested and executing all queries directly on SQLite within a dedicated native thread, ensuring that most queries are resolved in near real-time. Moreover, this innovative framework not only simplifies data management but also serves as a flexible solution for developers aiming to boost the overall performance and responsiveness of their applications, ultimately enhancing the user experience.
