Pushpin vs SocketCluster: What are the differences?
What is Pushpin? Reverse proxy for realtime web services. Pushpin is a reverse proxy server that makes it easy to build realtime web services. The project is unique among realtime push solutions in that it is designed to address the needs of API creators.
What is SocketCluster? An open, scalable realtime engine for Node.js. SocketCluster is a fast, highly scalable HTTP + realtime server engine which lets you build multi-process realtime servers that make use of all CPU cores on a machine/instance. It removes the limitations of having to run your Node.js server as a single thread and makes your backend resilient by automatically recovering from worker crashes and aggregating errors into a central log.
Pushpin and SocketCluster belong to "Realtime Backend / API" category of the tech stack.
Some of the features offered by Pushpin are:
- Supports HTTP streaming, HTTP long-polling, and WebSockets.
- Clients communicate using your API contract. Pushpin is a server-side implementation detail.
- Since Pushpin is a proxy server, the backend can be written in any language.
On the other hand, SocketCluster provides the following key features:
- Resilient on both the client and backend - Process crashes, lost connections and other failures are handled seamlessly.
- Scales linearly as you add more CPU cores and workers (assuming a decent OS) - Tested with up to 16 cores.
- Also designed to scale horizontally across multiple machines. See sc-redis sample.
Pushpin and SocketCluster are both open source tools. SocketCluster with 5.35K GitHub stars and 283 forks on GitHub appears to be more popular than Pushpin with 2.53K GitHub stars and 96 GitHub forks.
