SocketCluster vs Telepat: What are the differences?

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.

What is Telepat? Real time data synchronization platform for modern API driven web&mobile apps. Telepat is an open-source backend stack, designed to deliver information and information updates in real-time to clients, while allowing for flexible deployment and simple scaling.

SocketCluster and Telepat belong to "Realtime Backend / API" category of the tech stack.

Some of the features offered by SocketCluster are:

• 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.

On the other hand, Telepat provides the following key features:

• real-time sync
• query-able
• user auth

SocketCluster and Telepat are both open source tools. It seems that SocketCluster with 5.35K GitHub stars and 283 forks on GitHub has more adoption than Telepat with 340 GitHub stars and 20 GitHub forks.
