Compare Arrowchat and Twilio

Let’s compare Arrowchat and Twilio, looking at key elements of their offering such as their scalability, pricing, security and chat feature set.

Scalability
Concurrent connections

Number of users that can be supported in a single chat.

Arrowchat

Dedicated servers can run more than 1,000 online users, but shared servers can handle much less. Primarily built for 1-on-1 chats. Limits can be set by the administrator.

Twilio

1000 users can be supported per group.

Connections

Number of connections that can be handled across the platform.

Arrowchat

Unknown.

Twilio
  • Up to 7,000 in each Twilio subaccount.
  • 100,000 overall, shared among all your subaccounts.

Channels / rooms

Number of channels or rooms that can be handled across the platform.

Arrowchat

Unlimited.

Twilio

Unlimited.

Messages

Number of messages that can be handled across the platform.

Arrowchat

Twilio

Unlimited.

Message throughput

Number of messsages that can be published per second.

Arrowchat

Twilio

Unknown.

Data integrity
Guaranteed message delivery

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

Arrowchat

No

Twilio

No

Twilio does not provide exactly-once message delivery. While it 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.

Arrowchat

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.

Arrowchat

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.

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.

Arrowchat

None.

Twilio
  • Twilio APIs SLA: Up to 99.99%
  • Twilio Flex Critical Scenarios SLA: Up to 99.90%
  • Twilio Segment Data Ingestion API SLA: Up to 99.99%

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.

Arrowchat

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.

Arrowchat

No

Regardless of whether you opt for the self-hosted or paid-for hosted backend, ArrowChat cannot scale beyond one server.

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.

Arrowchat

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.

Arrowchat

Self-hosted version: Depends on the capacity of your server and other factors such as the bandwidth available to your hosting provider, as well as its location relative to your users. However, latency is likely to be poor due to ArrowChat’s reliance on a mix of short and long polling.

Hosted version: Not published.

Twilio

Unknown.

Server-side batching

Reduces the overall message count, lowers costs, and mitigates the risk of hitting rate limits during high-throughput scenarios.

Arrowchat

No

Twilio

No

Connection state recovery

Automatically re-establish failed connections and replay missed messages.

Arrowchat

No

Twilio

Yes

Twilio provides reconnection states and events for Twilio Video applications through the Twilio Video SDK.
