Our verdict on Ditto
Ditto is an embedded document database and edge synchronization platform for applications that need to keep operating without reliable connectivity. It is designed for mobile, desktop, web, and server environments across Windows, macOS, Linux, iOS, and Android. Its SDK supports Swift, Kotlin, JavaScript, C#, C++, Rust, Flutter, and React Native, making it relevant to teams building retail, hospitality, aviation, industrial, healthcare, and public-sector applications. The core use case is peer-to-peer and intermittently connected software that needs local data access and synchronization across devices.
Its standout capability is the combination of offline operation and distributed synchronization. Applications can perform reads and writes locally, then synchronize through Bluetooth Low Energy, peer-to-peer Wi-Fi, LAN, and cloud services. Self-organizing mesh networking and multi-hop synchronization allow data to move across intermediate devices, while automatic conflict resolution handles online and offline changes. Query-based synchronization subscriptions and reactive data observers add control over how applications receive and respond to data changes. The MongoDB bidirectional connector extends the platform into an existing MongoDB environment.
The freemium structure provides a Free tier with 10 cloud device connections, 2GB of included storage, 5GB of data transfer, no SLA, and limited customer support. Pro includes 1,000+ cloud device connections, 50GB of storage, a 99% uptime SLA, and Business Hours Support. Enterprise offers custom cloud device connections and storage, a 99.95% uptime SLA, and 24x7 support. Pro and Enterprise require contacting sales. Ditto should suit teams prioritizing offline-first behavior, peer synchronization, and multi-network resilience; teams needing a conventional centralized database or transparent paid pricing may prefer another option.
