Recommendation for out of box solution for subscription-based content platform?

Howdy -

I’ve been developing in rails for a bit, and technically could integrate
braintree or a similar payment processor with a rails app that also
handles
registration and has separate membership / roles attributes…

But hopefully there’s an already built in solution to just test a
minimal
viable product?

Features needed:

  1. Connect with Amazon web services to handle storage / streaming of
    files
  2. User registration with recurring subscription and self-subscribe /
    management
  3. Paygate functionality that controls access to certain pages / content
    and has easy freemium tier management / settings.

Does anything out there exist - free or paid - that can do the basics of
what I want? I’m looking for something similar to what wordpress has
with
s2member.

Let me know.

Thanks,
John

Have you seen the Rails Composer project, and the sample sites built
with it http://railsapps.github.io ? There’s a recurring payment system
version in there, ready to go.
