Collaborative data at the edge
Model complex state with simple building blocks. Nested objects sync in realtime, so local and remote state stay current.
Global realtime synchronization
Keep one logical copy of shared data. It replicates worldwide and stays in step across clients, even under heavy read/write load.
Always-available data
Objects are stored and replicated across regions. If a client drops, state is seamlessly restored on reconnection, without data loss or manual handling.
Consistent and conflict-free
Concurrent edits resolve automatically with conflict-free algorithms. You get eventual consistency at scale. No global locks or manual merges.
Massive scale, proven reliability
Built on Ably’s global edge network: no single failure point, 99.999% uptime SLA, and autoscaling to handle millions of users and spikes.
