I’ve been using Pusher as a websocket provider for several years now and have never experienced any breaking changes. I’m sure it’s cheaper to host my own, but

  Pusher is a bit more focused than what Now offered with its Serverless docker. You could containerize anything. So if you were putting MySQL or Redis in a container, and your main application depended upon that -- you were up a creek without a paddle. Pusher does Websockets. It can only be so opinionated, since it's a fairly focused, well-defined problem: Websockets. I'ts less likely to be subject to breaking changes versus Now. I'd say they have both roughly the same chance of randomly shutting down, with only a few months notice.
