Lift Framework vs Yii: What are the differences?
Developers describe Lift Framework as "The most powerful, most secure web framework available today". Lift creates abstractions that allow easier expression of business logic and then maps those abstractions to HTTP and HTML. This approach differs from traditional web frameworks which build abstractions on top of HTTP and HTML and require the developer to bridge between common business logic patterns and the underlying protocol. On the other hand, Yii is detailed as "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.
Lift Framework and Yii can be categorized as "Frameworks (Full Stack)" tools.
"Open source" is the primary reason why developers consider Lift Framework over the competitors, whereas "Open source" was stated as the key factor in picking Yii.
Lift Framework and Yii are both open source tools. It seems that Yii with 4.86K GitHub stars and 2.22K forks on GitHub has more adoption than Lift Framework with 1.19K GitHub stars and 270 GitHub forks.
