Ask HN: HipChat is shutting down, what should we replace it with?

We are team of ~10 people, mostly developers, we've used hipchat for years. Any opinions on what to switch to? We built a custom API plugin to add tasks to Asana, and we get messages from uptimerobot and capistrano when we deploy. Other than that, we just need something reliable and not too distracting. Any advice?
