Grails vs Trailblazer: What are the differences?
What is Grails? An Open Source, full stack, web application framework for the JVM. Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features.
What is Trailblazer? A new architecture for Rails. Trailblazer is a thin layer on top of Rails. It gently enforces encapsulation, an intuitive code structure and gives you an object-oriented architecture. In a nutshell: Trailblazer makes you write logicless models that purely act as data objects, don't contain callbacks, nested attributes, validations or domain logic. It removes bulky controllers and strong_parameters by supplying additional layers to hold that code and completely replaces helpers.
Grails and Trailblazer can be categorized as "Frameworks (Full Stack)" tools.
"Groovy" is the primary reason why developers consider Grails over the competitors, whereas "Trailblazer allows creating sane, large apps in Rails" was stated as the key factor in picking Trailblazer.
Grails and Trailblazer are both open source tools. It seems that Trailblazer with 2.91K GitHub stars and 129 forks on GitHub has more adoption than Grails with 2.48K GitHub stars and 945 GitHub forks.
