I was using Layer (layer.com), but their monthly plans just went up drastically, and it would break the bank for me to stay with them. Can anyone recommend any other Chat SDKs? It doesn't have to be free, just not $600/month. The key things for me are: Push Notifications Attractive/customizable UI (the better the default or sample ones the better) If you can recommend a chat service I can install on my server (currently parse, but will be building out my own parse server on AWS in the future), I'm open to that too.
