I was curious about Chris McCord's Phoenix vs Rails article -- if you haven't read it, go do that now first. Go ahead, this will still be here when you get back. It won't make much sense unless you've read the original. Like many other Elixir enthusiasts, I come from a Ruby background. That said, I found Rails to be a curious choice for comparison to Phoenix, since Rails is really a kitchen-sink framework meant to handle everything from database migrations to asset-pipeline compilation. Sinatra, on the other hand, is a more modular, semi-minimal framework that is appears to be pretty close in philosophy to what Phoenix looks like at the moment (at least to me).
