Compare Quickblox and Stream
Let’s compare Quickblox and Stream, 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. | Quickblox Limit on pre-enterprise plans is 25,000. There is no specified limit on Enterprise. Read more | Stream 2500 users supported in a single chat. Supported within Start and Elevate packages. Overages apply if you exceed plan quota - $0.79 per additional concurrent user. Read more |
Connections | Number of connections that can be handled across the platform. | Quickblox Unknown. | Stream |
Channels / rooms | Number of channels or rooms that can be handled across the platform. | Quickblox Unlimited. | Stream Unlimited. |
Messages | Number of messages that can be handled across the platform. | Quickblox Unknown. | Stream Unlimited. |
Message throughput | Number of messsages that can be published per second. | Quickblox | Stream 5 messages per second. When concurrent connections exceeds 100 in a group messages are throttled to 5 per second. |
| Data integrity | |||
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | Quickblox No | Stream 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. | Quickblox No | Stream 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. | Quickblox No | Stream 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. | Quickblox Unknown. | Stream
|
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. | Quickblox No | Stream Yes Stream has data centers located around the world, including:
|
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. | Quickblox No | Stream 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. | Quickblox No | Stream Yes Stream's chat infrastructure does not rely on a single data center due to global edge network support, thus avoiding a single point of failure and congestion. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | Quickblox Unknown. | Stream Stream does not provide a global latency figure. However, it achieves a region-based average roundtrip latency of 170 ms between Amsterdam and the US East. |
Server-side batching | Reduces the overall message count, lowers costs, and mitigates the risk of hitting rate limits during high-throughput scenarios. | Quickblox No | Stream |
Connection state recovery | Automatically re-establish failed connections and replay missed messages. | Quickblox Yes QuickBlox Chat SDKs support automatic reconnection and offline message queuing, which ensures that when the connection is lost, messages are held on the server and delivered once the connection is re-established. Read more | Stream Yes Stream SDKs automatically attempt to recover the connection and ensure that a connection to Stream chat is always kept alive. That chat state is recovered when the user's internet connection comes back online. |
| Ecosystem support | |||
