Best Offline-First Databases

Ditto is an offline-first mobile database that ensures data is always available locally and stays consistent across devices—even in completely disconnected environments. At its core, Ditto uses Conflict-Free Replicated Data Types (CRDTs) to automatically resolve conflicts and guarantee strong eventual consistency, without requiring developers to write custom merge logic. But Ditto doesn’t stop where most offline-first databases do. We go further by making offline-first apps to synchronize even when completely offline. Ditto is the only offline-first database that includes built-in peer-to-peer and mesh networking, allowing devices to sync directly with one another without any cloud or server infrastructure. When a network connection is unavailable, Ditto-enabled devices can discover and sync with nearby peers using Bluetooth, peer-to-peer Wi-Fi, LAN, or cellular—ensuring real-time updates, even in edge environments.

Berkeley DB is a family of embedded key-value database libraries providing scalable high-performance data management services to applications. The Berkeley DB products use simple function-call APIs for data access and management. Berkeley DB enables the development of custom data management solutions, without the overhead traditionally associated with such custom projects. Berkeley DB provides a collection of well-proven building-block technologies that can be configured to address any application need from the hand-held device to the data center, from a local storage solution to a world-wide distributed one, from kilobytes to petabytes.

The superfast nosql database for mobile and iot with integrated data synchronization. High-performance Objectbox is 10x faster than any alternative, improving response rates and enabling real-time applications. Check out our benchmarks. From sensor to server and everything in between. We support linux, windows, mac/ios, android, raspbian, etc. Embedded or containerized. Sync data seamlessly. Objectbox’ out-of-the-box synchronization makes data available when needed where needed, so you can take your app live faster. Offline first Develop applications that work on- and offline, independently from a constant internet connection, providing an “always-on”-feeling. Save time & dev. resources. Accelerate time-to-market, save development and lifecycle costs, save precious developer time for tasks that bring value, and let objectbox deal with the risk. Objectbox reduces cloud costs up to 60% by persisting data locally (on the edge), and syncing necessary data quicker and more efficiently.

Actian Zen is an embedded, high-performance, and low-maintenance database management system designed for edge applications, mobile devices, and IoT environments. It offers a seamless integration of SQL and NoSQL data models, providing flexibility for developers working with structured and unstructured data. Actian Zen is known for its small footprint, scalability, and high reliability, making it ideal for resource-constrained environments where consistent performance and minimal administrative overhead are essential. With built-in security features and a self-tuning architecture, it supports real-time data processing and analytics without the need for constant monitoring or maintenance. Actian Zen is widely used in industries like healthcare, retail, and manufacturing, where edge computing and distributed data environments are critical for business operations.

Unlike other NoSQL databases, Couchbase provides an enterprise-class, multicloud to edge database that offers the robust capabilities required for business-critical applications on a highly scalable and available platform. As a distributed cloud-native database, Couchbase runs in modern dynamic environments and on any cloud, either customer-managed or fully managed as-a-service. Couchbase is built on open standards, combining the best of NoSQL with the power and familiarity of SQL, to simplify the transition from mainframe and relational databases. Couchbase Server is a multipurpose, distributed database that fuses the strengths of relational databases such as SQL and ACID transactions with JSON’s versatility, with a foundation that is extremely fast and scalable. It’s used across industries for things like user profiles, dynamic product catalogs, GenAI apps, vector search, high-speed caching, and much more.

Ultrafast, scalable, embeddable SQL database with commercial-grade data security, disaster recovery, and change synchronization. Cross-platform, zero-install, embedded database as a direct-access library. Cross-platform, zero-install, embedded database with database-level and column-level AES and DES encryption. Concurrent applications/client access to the database on Windows with database-level and column-level AES and DES encryption. Ultrafast, scalable, SQL server database for Windows and Linux with commercial-grade data security, disaster recovery and change synchronization. Attacks on databases and loss of data can be costly and lead to loss of customers’ trust (and business), regulatory action, and heavy fines. InterBase provides over-the-wire and at-rest encryption, separate security login, and role-based user security. InterBase maintains full on-disk encryption while adding negligible overhead to database speed and performance.
