PubNub vs TalkJS

Number of connections that can be handled across the platform.

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

Number of messages that can be handled across the platform.

Number of messsages that can be published per second.

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.

Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages.

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.

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.

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.

Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience.

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

Automatically re-establish failed connections and replay missed messages.

Supporting multiple languages and platforms offers greater flexibility when building cross-platform realtime apps.
