A lot of the tooling is Ruby-like. Phoenix and Rails are very similar as well.

They do have some major fundamental differences though and I think the similarity is often overstated.

Phoenix is similar to Rails superficially, I’m so far as they both have some MVCish structure and some generators. The similarities really stop there though.

Phoenix doesn’t have a magical asset pipeline, it doesn’t have a whole library of language extensions a la ActiveSupport, it doesn’t represent dB rows as objects. Those are just a few things off the top of my head.

Additionally all requests to an app running Phoenix/Cowboy/Plug are separate processes and can happen in parallel without having to stand up multiple app instances.
