Ditto vs. RxDB Comparison Chart

Ditto is an embedded database designed for mobile and edge devices that goes far beyond local storage. Unlike traditional embedded databases that operate in isolation, Ditto comes with built-in peer-to-peer sync and edge-aware connectivity, enabling devices to synchronize data without relying on a central server or constant internet access. At the core of Ditto is a CRDT-based (Conflict-Free Replicated Data Type) engine that guarantees strong eventual consistency across distributed nodes—even in fully offline, partitioned, or mobile-first environments. This allows developers to build highly resilient and collaborative applications where data is always local, yet automatically synchronized across devices when connections become available. Ditto abstracts the complexity of connectivity with dynamic, channel-agnostic discovery. Devices running Ditto form ad-hoc mesh networks using Bluetooth, peer-to-peer Wi-Fi, LAN, cellular, or any combination syncing data changes in real-time.

Ditto is an offline-first mobile database designed to integrate seamlessly into your existing apps—bringing always-available data, peer-to-peer sync, and edge resiliency to even the most connectivity-challenged environments. With Ditto, you can retrofit your current mobile stack with modern offline capabilities. Instead of relying on constant cloud access or fragile network connections, Ditto enables your app to function reliably in fully offline conditions. Its built-in synchronization engine uses peer-to-peer and mesh networking to keep devices in sync—no central server required. Whether your users are on the move, underground, airborne, or simply outside Wi-Fi range, Ditto ensures their data is always up-to-date and shared in real time with nearby devices. Sync happens automatically over Bluetooth, peer-to-peer Wi-Fi, LAN, or cellular—whichever connection is available. You don’t need to write custom sync logic or manage conflict resolution: Ditto handles it all for you.

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.
