Occupancy | High-level metrics about the clients currently connected to a channel make it simple to show things such as connected user count, or display which channels are the most popular. | OneSignal No | Socket.IO |
Message interactions | Enables interaction with previously-sent messages, facilitating the implementation of features like message reactions and threads. | OneSignal No | Socket.IO Partial You would need to build the message interaction functionality yourself on top of Socket.IO. Learn more |
Message history | Enables clients to catch up on missed messages when inactive, ensuring a user doesn’t miss any important messages. | OneSignal No OneSignal does not offer an archive of messages for retrieval. However, it provides notification history, which is different from message history. The notification history focuses on the records of notifications sent. | Socket.IO No The Socket.IO server does not store messages. Your application has to persist messages somewhere for the clients that are not currently connected. Learn more |
Push notifications | Cross-platform push notifications make it possible to deliver important and timely messages to users even when they’re inactive. | OneSignal Yes OneSignal offers push notifications for both mobile and web platforms. | Socket.IO No Socket.IO not support Push notifications. You would need to build this capability yourself and/or use another library. Learn more |

| Quality of Service | |||
Scalability | Scalability is vital as it ensures the service can handle increased data load or users without compromising performance. | OneSignal OneSignal can deliver a throughput of over 850,000 notifications per second, which relatively equates to 4 billion push notifications daily. It has also been able to scale its database to 75 terabytes (TB) of stored data across nearly 40 servers. Read more | Socket.IO No published metrics. Socket.IO servers don’t communicate between them, so you need a way to route events to all clients, even if they are connected to different servers. This is made possible by using adapters, of which the Redis adapter seems to be the most popular choice. |
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | OneSignal No OneSignal does not guarantee message delivery. It only offers confirmed deliveries. That means it does not handle retries in the event of failures, and the message may not be delivered. | Socket.IO Partial By default, Socket.IO provides an "at most once" guarantee of delivery. From the client side, you can achieve an at least once guarantee with acknowledgements and timeouts. |
Guaranteed message ordering | Maintains the sequence of messages as they were sent. This is particularly important in apps where the chronological order of messages is essential for meaningful communication. | OneSignal No | Socket.IO |
Exactly-once message delivery | Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages. | OneSignal No | Socket.IO No At least once or at most once only. |
| Performance & availability | |||
Uptime Guarantee | An uptime guarantee instills confidence in the reliability of the service and protects your business from the negative impacts of downtime. | OneSignal Not publicly mentioned. | Socket.IO No It is a library, not a platform. |
Global edge network | By bringing servers (Points of Presence, or PoP) geographically closer to the devices of end users, and routing requests to the nearest PoP, global latency is reduced to a minimum. | OneSignal No | Socket.IO 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. | OneSignal No OneSignal locates its datacenters in the EU, and it's unclear if they support multi-region data replication. Read more | Socket.IO 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. | OneSignal No | Socket.IO No As Socket.IO is a library, the implementation of it dictates points of failure and congestion. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | OneSignal Unknown. | Socket.IO Unknown |
| Security & compliance | |||
API key authentication | Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens. | OneSignal | Socket.IO No |
