Guaranteed message delivery

Ensures messages are never lost during transmission, even in the presence of network disruptions.

Supabase Realtime

No

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.

Supabase Realtime

Yes

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.

Supabase Realtime

Yes

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.

Supabase Realtime

Yes

Multi-region data replication is natively supported in Supabase through their Publications feature.

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.

Supabase Realtime

Yes

Supabase provides a globally distributed cluster of realtime servers. The realtime servers are designed to be highly available and fault-tolerant.
