Pusher

No

Rails ActionCable

No

Multi-region data replication (message durability)

By replicating data across multiple regions, the risk of data loss or downtime is greatly mitigated since if data is lost or a server fails in one region, the information can be retrieved from another.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. Any latency issues that occur in that data center will affect all apps hosted there.

Rails ActionCable

No

No single point of failure or congestion

Having no single point of failure means a system is resilient and can continue to operate even if one part fails. Avoiding a single point of congestion ensures messages flow efficiently across the system and avoids bottlenecks that could lead to performance issues under load.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. If that data center goes offline then all apps hosted there are affected.

Rails ActionCable

No

Latency

Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience.

Pusher

Not shared. Because apps exist in only one region, message latencies increase for clients the further they are from your chosen data center.

Rails ActionCable

Unknown.

Security & compliance
API key authentication

Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens.

Pusher

Yes

Rails ActionCable

No
