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. Read more | Twilio 1000 users can be supported per group. |
Connections | Number of connections that can be handled across the platform. | Arrowchat Unknown. | Twilio
|
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 Unknown. | Twilio Unlimited. |
Message throughput | Number of messsages that can be published per second. | Arrowchat Unknown. | 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. 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. | Arrowchat None. | 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. | 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. Read more |
