While I was building Neeyer (<a href="https://neeyer.com" rel="nofollow">https://neeyer.com</a>), a location based social app, which I'll do another post later. I found it hard to find a managed Websocket service without vendor lock-in. So I built myws.dev and been using it for my app.<p>I know this is something I'd use myself (and I AM using it). So I hope this helps you too focus on your own app instead of infrastructure.
