Compare Arrowchat and Sendbird
Let’s compare Arrowchat and Sendbird, 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 | Sendbird Up to 20K users in super groups are supported in a single chat. Overages apply if you exceed plan quota - $5 per additional concurrent connection. |
Connections | Number of connections that can be handled across the platform. | Arrowchat Unknown. | Sendbird Unlimited - depends on plan. Overages apply if you exceed plan quota - $0.05 per additional user. |
Channels / rooms | Number of channels or rooms that can be handled across the platform. | Arrowchat Unlimited. | Sendbird Unlimited. |
Messages | Number of messages that can be handled across the platform. | Arrowchat Unknown. | Sendbird Unlimited. |
Message throughput | Number of messsages that can be published per second. | Arrowchat Unknown. | Sendbird 5 messages per second. |
Data integrity | |||
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | Arrowchat No | Sendbird No |
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 | Sendbird No |
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 | Sendbird No |
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. | Sendbird A 99.9% SLA uptime guarantee is provided on paid plans. |
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 | Sendbird Yes Sendbird has servers deployed across 11 worldwide regions. |
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. | Sendbird 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. | Arrowchat No | Sendbird No |
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. | Sendbird 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 | Sendbird No |
Connection state recovery | Automatically re-establish failed connections and replay missed messages. | Arrowchat No | Sendbird Yes Sendbird implements connection state recovery through their chat SDKs, which are designed to automatically handle reconnections and message delivery. |
Ecosystem support | |||
