I would like to point out that there exists solutions tested in the field in the last 20 years to solve the same problem.

In particular I would suggest to get to know MQTT an open protocol with several (open and close) implementation that is know for its flexibility and scalability (if nothing has changed it is used to power the Messager Facebook platform, but don't quote me on that).

verneMQ is the server implementation I would suggest if you are interested in such topic.

MQTT is just a protocol, not a service. I don't think it was the developer's intention to provide an alternative to MQTT, but to offer a solution for push-notifications, which just happens to be built on top of WebSocket without MQTT. Also keep in mind that MQTT will usually get wrapped by WebSocket to avoid issues with firewalls or to easily get TLS via a proxy server like NGINX, or simply to add web browser support. VerneMQ is not the only server implementation for MQTT.

Depends on the exact problem definition. This is a small, single-binary server, offering a built-in web UI & API, requiring very little configuration, working with a mobile app for Android phones. Took me 5 minutes to start getting some notifications from things around my house.

Sometimes you don't need a cargo van or a jumbo jet to get the job done when a skateboard will do.
