Sinatra makes ruby dramatically more useful with its incredibly easy post and get extensions as well as the simple inclusion and transmission of parameters. Traditional Ruby on Rails (ROR) meant that our team had to do a lot of running around to get our in-house restful-js api to post to our payment server. What's most notable about Sinatra is just how easy it is to setup. While our previous payment api took almost a year to develop and pass quality control testing, Sinatra was completed in roughly 5 months, which was a dramatic but very welcome change from our previous implementation.

Quite simply (as you can tell by the name), the framework can be a bit cheesy at times, making several references to Frank Sinatra before, during, and after compilation. However, this is dramatically outweighed by the functionality of the contract. Review collected by and hosted on G2.com.
