Sinatra is a great way to build test programs and demos. Once scaling up to a real application I have found that Rails is a better choice because it has a lot of the things built in that feel missing from Sinatra. For example if you are trying to figure out how to add things like flexible initialization logic, security protections, clever MIME type handling, Cucumber testing, and better routing, you’ll find that Rails has these things built in. What you can’t get from Rails is the “one file application” that’s the killer feature of Sinatra. But all those files and directories in Rails are doing stuff that you’ll eventually want.
