Ruby on Rails is a mature web application framework favored for its rapid development capabilities and rich ecosystem, making it suitable for a wide range of web applications. In contrast, CUBA.platform is tailored for enterprise applications, providing built-in UI components and strong support for business processes, but it may lack the same level of flexibility and customization as Rails.
