For those that are feeling fatigued from working with and around the magic of Rails, Sinatra is a great choice (in python land Django has an alternative called Flask).<p><a href="http:&#x2F;&#x2F;www.sinatrarb.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.sinatrarb.com&#x2F;</a><p>That said, you will have to re-implement machinery that rails gave you for free. If you&#x27;re building a simple API, there will be obvious simplicity benefits. If you&#x27;re trying to build a server-side rendered web application, you may long for some things that rails provided (of course, you can use libraries and create simpler patterns than rails provided).<p>Note that going the sinatra+libs (or any &quot;micro&quot; framework for that matter) route places a higher burden on the development team when it comes to documentation. If you implement a scheme for server side templating&#x2F;rendering outside of what is provided, you will be in a world of pain in a relatively short time if you do not maintain good documentation.
