(author here) It only uses Sinatra because I happened to know it and needed to bootstrap the low-level stuff. I don't know if it needs to be based on Sinatra in the long term - it should probably just use Rack.
Thanks for the reply. Interesting that you mention that it should just use Rack. It reminds me of a time a number of years ago where I was on a mission to use a framework which did not have a million and one dependencies, but just Rack.
Not sure you have come across https://github.com/Ramaze/innate (I am showing my age now :) . It is the core of the Ramaze framework. I really liked the philosophy of that project. Its a shame it never caught on though.
