Provides multiplayer-by-default synchronization with immediate state updates across devices, as demonstrated in the quickstart examples where data changes propagate in real-time.

Supports key/value, tables, documents, and more within a unified graph structure, allowing circular references and complex data models without schema constraints.

Decentralized design with end-to-end encryption ensures data availability without constant connectivity, crucial for collaborative apps in low-network environments.

Optimized engine claims over 20 million API operations per second in a 9KB gzipped package, making it suitable for resource-constrained devices.
