|
| Integrations & interoperability | |||
SDKs | Supporting multiple languages and platforms offers greater flexibility when building cross-platform realtime apps. | OneSignal
| Twilio
|
Supported realtime protocols | Support for multiple protocols provides the flexibility to choose a protocol that best suits your project’s requirements. | OneSignal None. | Twilio
|
Serverless functions | Enables integration with third-party cloud providers by facilitating the execution of custom code against messages to perform business logic like on-the-fly translation. | OneSignal None. | Twilio
|
Streaming & queueing | Provides a dependable method to reroute messages from the service to third-party streams and queues for further processing. | OneSignal No OneSignal provides queuing for messages and notifications but lacks proper streaming and queuing support. OneSignal's Live Activities and Event Webhooks simulate stream-like behavior, though real streaming requires integration with other services. | Twilio Yes |
Observability services | Enables realtime monitoring and troubleshooting by offering insights into service behavior directly in your observability platform of choice. | OneSignal Yes OneSignal offers observability features, such as tracking notifications, user engagement metrics, and delivery reports. | Twilio Yes Twilio provides observability through insights and monitoring dashboards for voice, messaging, and flex. The dashboards give metrics like time range, delivery status, messaging traffic, errors, responses, etc. |
CI/CD tools | Makes it possible to provision and configure service infrastructure as part of a CI or CD pipeline, enabling repeatable and reliable deployments. | OneSignal No | Twilio No |
| 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 | Twilio
|
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. | Twilio Yes While Twilio ensures reliable delivery, it typically follows at-least-once or best-effort delivery models. That means messages may be delivered more than once in rare cases, such as during network failures or retry attempts. |
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 | Twilio No Twilio sends SMS messages in the order they are queued, but they are delivered individually. That means that if you send multiple SMS messages to the same user quickly, Twilio cannot guarantee that the messages will arrive in the order you sent them. Read more |
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 | Twilio No Twilio doesn't guarantee exactly-once delivery by default. However, it can implement de-duplication in the receiving service by checking if an event with the same ID has already been received, and discarding duplicates. Read more |
| 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. | Twilio
|
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 | Twilio Yes Twilio has a global edge network of network edges called Twilio Edge Locations, which allows you to control the geographic location where your application's network traffic enters and exits Twilio's platform. |
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 | Twilio Yes Twilio provides multi-region data replication to enhance message durability. |
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 | Twilio Yes Twilio's "Super Network" and hybrid cloud infrastructure reduce the risk of a single point of failure and congestion. The design is built with redundancy and scalability to minimize potential disruptions. |
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. | Twilio Unknown. |
