Ruby on Rails

What Ruby on Rails is

Ruby on Rails is a free, open-source full-stack framework for building web applications with Ruby. Ruby is its primary language, and the framework supports server-side rendering. An included object-relational mapper provides ORM support within the application framework, combining application structure with data handling. Rails targets the web and lists self-hosted deployment, so teams can build applications intended to run on infrastructure they control. The listed pricing model is free, with a free plan noted. Its scope is defined by web application development, server-rendered output, Ruby programming, and integrated data mapping. Developers can therefore use one open-source framework for a full-stack web project rather than selecting separate tools for these listed roles. Ruby on Rails is presented as a framework rather than a hosted service, with deployment responsibility remaining on the project team.
