When comparing Catberry vs FeathersJS, the Slant community recommends FeathersJS for most people. In the question“What are the best full-stack isomorphic JavaScript frameworks?” FeathersJS is ranked 2nd while Catberry is ranked 4th. The most important reason people chose FeathersJS is:
Feather can sync events happening in two different Node processes or even servers in real-time. For example: an event happens in server A, the user connected to server B is instantly notified of that event. This is done through a central Redis or Mongo collection or through a websocket libraries' clustering library.

Pros
Pro Views are rendered on the server progressively
Catberry employs server-side progressive rendering to render its views in the browser. This is achieved through Node's streams and parallel rendering.
Pro Easy to understand how a Catberry application works even when it starts getting complicated
Flux is a platform agnostic pattern which can technically be used with any application or programming language.
One of Flux' main features is that it enforces uni-directional data flow which means that views do not change the data directly.
This is useful because this way it's easier to understand an application as it starts getting more complicated. By having two-way data binding, it can lead to unpredictable changes, where changing one model's data would end up updating another model. By using the Flux architecture, this can be avoided.
Pro SEO friendly
The search crawler receives the rendered page from the server just like a normal user would. This makes applications developed with Catberry very SEO-friendly.
Pro Can sync events between different Node instances
Feather can sync events happening in two different Node processes or even servers in real-time. For example: an event happens in server A, the user connected to server B is instantly notified of that event.
This is done through a central Redis or Mongo collection or through a websocket libraries' clustering library.
Pro Easy REST APIs
Through services, Feathers provides instant CRUD functionality, it also can easily expose a RESTful and real-time API through HTTP/HTTPS and websockets.
Pro Can be integrated in an existing ExpressJS project
Since Feathers itself is built on top of Express (it's a thin wrapper over socket.io, primus and Express) and because of Feathers' highly modular nature, it's very easy to integrate Feathers in an existing Express project.
Pro Plug-in any feature you need
Feathers makes extensive use of modules (which are called Feathers services). These services work like ExpressJS middleware and can be used with app.use('/path', serviceObject)
.
Services help developers keep their applications modular and as minimal as possible, without any unnecessary libraries or bloat.
Pro Support for different socket transports
FeatherJS uses primus which is a universal wrapper for real-time frameworks. Through primus you can easily choose which socket transport you want to use.
Cons
Con Seems to be very popular only in non-English speaking countries
Catberry seems to be very popular in countries where English is not a native language (for example Russia). For this reason it can be very hard to find any resources in English outside the Catberry website.
Con Not so widely used
Could be problematic to convince the client use this framework in his/her project.
Con Not very beginner friendly
Although the documentation for Feathers is very good, it still needs some configuration in order to get Feathers up for developing something with it.
