Atmosphere vs Trailblazer: What are the differences?
What is Atmosphere? Realtime Client Server Framework for the JVM, supporting WebSockets and Cross-Browser Fallbacks Support. The Atmosphere Framework contains client and server side components for building Asynchronous Web Applications. The majority of popular frameworks are either supporting Atmosphere or supported natively by the framework. The Atmosphere Framework supports all major Browsers and Servers.
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.
Atmosphere and Trailblazer can be primarily classified as "Frameworks (Full Stack)" tools.
"Cross-Browse" is the top reason why over 2 developers like Atmosphere, while over 3 developers mention "Trailblazer allows creating sane, large apps in Rails" as the leading cause for choosing Trailblazer.
Atmosphere and Trailblazer are both open source tools. It seems that Atmosphere with 3.34K GitHub stars and 720 forks on GitHub has more adoption than Trailblazer with 2.91K GitHub stars and 129 GitHub forks.
