Everyone has been happy to jump in on the Ruby on Rails craze, with its rapid development benefits converting many developers from other web development platforms. However, not all web hosts provide RoR in their list of services. Only the big guys like Dreamhost come with Rails.
For someone just trying out RoR development, you can always deploy a local server on your desktop for coding and debugging. However, at some point the need for testing your code in the wild is a must. Hosting Rails allows you to just that, providing free rails hosting along with their affordable web hosting packages. If you’re evaluating RoR, their free hosting plan will be good enough for your needs.
