We’ve been using Phoenix at my company in production for over a year now. So far the experience has been overwhelmingly positive, our team have totally come round to its adoption, our server costs have come down and our response times have gone down also.

Coming from Rails, the ecosystem isn’t quite there yet, but it is far more mature than rails’ was this early on.

The hardest thing for us has been deployment, but we’ve solved that internally, including giving back by building exrm_deb (it works with distillery too!) to compile the entire project into a Debian package.

If you haven’t already looked at Phoenix (and Ecto!) give it a try :)
