Compare Quickblox and TalkJS
Let’s compare Quickblox and TalkJS, 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 | TalkJS 300 users can be supported in a single chat. Limits for Enterprise plan are unknown. |
Connections | Number of connections that can be handled across the platform. | Quickblox Unknown. | TalkJS 25,000 connections can be handled across the platform. Users would need to opt for the Enterprise plan for higher rates. |
Channels / rooms | Number of channels or rooms that can be handled across the platform. | Quickblox Unlimited. | TalkJS Unlimited. |
Messages | Number of messages that can be handled across the platform. | Quickblox Unknown. | TalkJS Unlimited. |
Message throughput | Number of messsages that can be published per second. | Quickblox | TalkJS 9 messages/second rate limit. Read more |
Data integrity | |||
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | Quickblox No | TalkJS 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 | TalkJS 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 | TalkJS Yes TalkJS guarantees that messages are sent exactly-once via an idempotency key regardless of any number of retries. |
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. | TalkJS TalkJS guarantees an uptime of 99.9%/month, only available for Enterprise customers. |
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 | TalkJS No TalkJS servers are only located in the European Union. |
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 | TalkJS |
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 | TalkJS 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. | Quickblox Unknown. | TalkJS Unknown. |
Server-side batching | Reduces the overall message count, lowers costs, and mitigates the risk of hitting rate limits during high-throughput scenarios. | Quickblox No | TalkJS No |
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.
