Read more
Pusher

Yes

Occupancy

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.

Firebase

Partial

Firebase does not have built-in support for occupancy tracking. However, occupancy tracking functionality can be built on top of the Firebase Realtime Database.

Pusher

Firebase

No

Pusher

No

Pusher does not offer any message history functionality. But Cache Channels stores the last event sent to the channel - it is stored for a max of 30 min or until a new event arrives. This can be useful in some use cases.

Push notifications

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

Firebase

Quality of Service
Scalability

Scalability is vital as it ensures the service can handle increased data load or users without compromising performance.

Firebase

Firebase Realtime Database is limited to 200,000 simultaneous connections, 1000 Cloud Functions per write (500 for v2 per region), 1 MB event size, and 10 MB/sec data transfer to Cloud Functions.

Pusher

No scalability metrics published.

Guaranteed message delivery

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.

Firebase

Yes

Firebase benefits from Google's global edge network.

Pusher

No

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.

Firebase

No

Multi-region data replication is currently not supported in Firebase Realtime Database, but it is supported in Firestore databases.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. Any latency issues that occur in that data center will affect all apps hosted there.

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.

Firebase

No

Each Realtime Database instance is tied to a single region chosen at the time of creation.

Pusher

No

Pusher apps are located in a single data center rather than distributed across multiple data centers. If that data center goes offline then all apps hosted there are affected.

Latency

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

Firebase

Unknown.

Pusher

Not shared. Because apps exist in only one region, message latencies increase for clients the further they are from your chosen data center.

Security & compliance
API key authentication

Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens.

Firebase

No

Pusher

Yes

Token-based authentication

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

Firebase

Yes

Supported with JSON Web Tokens (JWTs).

Read more
Pusher

Yes

Single Sign-On (SSO) authentication

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

Pusher

Partial

Requires you to implement an endpoint they will call to check if operation is allowed.

End-to-end encryption

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

Firebase

Data in transit is encrypted using HTTPS in all Firebase services, but this does not include end-to-end encryption.

Read more
Pusher

Yes

Encryption at rest

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

Firebase

Partial
