PubNub vs Pusher

Accelerates the time to implement rich chat experiences with features such as read receipts, typing indicators, and more.

Enables you to quickly integrate realtime collaborative features like live cursors, member location, avatar stacks, and component locking.

Enables realtime data synchronization across devices and users, ensuring a cohesive and up-to-date user experience.

Maintaining a view of which users are connected, and their associated metadata, enables their online status to be updated in realtime.

High-level metrics about the clients currently connected to a channel make it simple to show things such as connected user count, or display which channels are the most popular.

Enables interaction with previously-sent messages, facilitating the implementation of features like message reactions and threads.

Enables clients to catch up on missed messages when inactive, ensuring a user doesn’t miss any important messages.

Cross-platform push notifications make it possible to deliver important and timely messages to users even when they’re inactive.

Minimizes bandwidth and can reduce latency, particularly in scenarios where continuous updates are sent.

Enables the automation of provisioning, management, and testing of service resources, simplifying integration with existing development workflows such as CI.

The pricing model should align with your project's expected load, usage patterns, and budget in order to be cost-effective and efficient.

Support for multiple protocols provides the flexibility to choose a protocol that best suits your project’s requirements.

Enables integration with third-party cloud providers by facilitating the execution of custom code against messages to perform business logic like on-the-fly translation.

Provides a dependable method to reroute messages from the service to third-party streams and queues for further processing.

Enables realtime monitoring and troubleshooting by offering insights into service behavior directly in your observability platform of choice.

Makes it possible to provision and configure service infrastructure as part of a CI or CD pipeline, enabling repeatable and reliable deployments.

Ensures messages are never lost during transmission, even in the presence of network disruptions.

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.

Provides a means to securely authenticate user devices against your user management system.

SSO streamlines login processes, boosts security by minimizing password use, and meets compliance needs for secure data access management.

Provides control over which users can subscribe and publish to certain channels.

Ensures that the data transmitted between the client and the API server remains confidential and secure while in transit.

Ensures data stored by the service is secure and compliant, while also mitigating the risks of a data breach.

Compliance with regulations can impact your ability to meet legal obligations in your industry.
