Trailblazer vs Yii: What are the differences?
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.
What is Yii? A high-performance PHP framework best for developing Web 2.0 applications. Yii comes with: MVC, DAO/ActiveRecord, I18N/L10N, caching, authentication and role-based access control, scaffolding, testing, etc. It can reduce your development time significantly.
Trailblazer and Yii can be primarily classified as "Frameworks (Full Stack)" tools.
"Trailblazer allows creating sane, large apps in Rails" is the primary reason why developers consider Trailblazer over the competitors, whereas "Open source" was stated as the key factor in picking Yii.
Trailblazer and Yii are both open source tools. Yii with 4.86K GitHub stars and 2.22K forks on GitHub appears to be more popular than Trailblazer with 2.91K GitHub stars and 129 GitHub forks.
