SocketCluster vs Streamdata.io: What are the differences?

Developers describe SocketCluster as "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. On the other hand, Streamdata.io is detailed as "Efficiently Turn APIs into Real-time Experiences". Streamdata.io is a real-time cache proxy allowing you to poll JSON REST APIs and push updates to clients. Streamdata.io also keeps a history of modifications that occur on the data between two pollings. This way, streamdata.io is able to give you the list of modifications which happened since last time you fetched the data.

SocketCluster and Streamdata.io can be primarily classified as "Realtime Backend / API" tools.

SocketCluster is an open source tool with 5.35K GitHub stars and 283 GitHub forks. Here's a link to SocketCluster's open source repository on GitHub.
