Would you say that Plug is the Rack of Elixir?

[rubiquity]

Yes that's exactly the domain that Plug sits in. It's an interface from web servers to applications. As someone who tinkered around with Rack and Ruby web servers a lot, Plug is much better designed (yay for learning from past implementations).

I'd even say that Phoenix is more akin to Sinatra than to Rails.
