List of the Top 4 Offline-First Databases for Android in 2025

Ditto is a mobile database designed for offline use, ensuring that data remains accessible locally and synchronized across different devices, even in environments without internet connectivity. At its foundation, Ditto utilizes Conflict-Free Replicated Data Types (CRDTs) to automatically handle data conflicts, providing strong eventual consistency without the need for developers to implement custom merging solutions. However, Ditto goes beyond the capabilities of typical offline-first databases. It facilitates seamless synchronization for offline-first applications, even when devices are entirely disconnected. Unique to Ditto is its integrated peer-to-peer and mesh networking capabilities, which enable devices to sync directly with each other without relying on cloud services or server infrastructure. When there is no network connection, Ditto-enabled devices can locate and sync with nearby peers through Bluetooth, peer-to-peer Wi-Fi, LAN, or cellular connections, ensuring that real-time updates are possible, even in challenging environments.

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.
