Pusher Channels: Pricing, Features & Alternatives

Pusher Channels is the long-standing default for 'make this screen update without a refresh'. You publish to a channel, connected clients receive it, and Pusher operates the socket infrastructure. It is realtime transport rather than notification orchestration: no templates, no per-user preferences, no email fallback — but for live dashboards, collaborative cursors and in-app toasts it is a few lines of code.
