Phalcon vs FeathersJS

Since the framework is and extension built in C it's extremely fast and efficient. It's actually one of the fastest PHP frameworks, and according to some benchmarks it's the fastest framework out there.

Phalcon is open source and is available under the BSD License.

The Volt template engine, which is embedded into Phalcon itself takes it's inspiration from the Jinja template engine and as such it's nice to look at, with a clear and understandable syntax.

Volt also compiles very fast, like Phalcon itself, so it avoids being a bottleneck for the framework's overall speed.

You can set up the base project as you want. It's very flexible

Since the framework code is not in the project directory, the code is light and clean.

Zephir is a high-level language designed to create PHP extensions easily by PHP programmers with no knowledge in C.

Zephir does this by compiling directly to C and then the C program is in turn compiled to be run as a PHP extension. This, coupled with the fact that Zephir's syntax is very similar to PHP makes it a perfect way for PHP developers to use it for customizing Phalcon.

Some components can be used as standalone packages like models, views, etc..

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.

Through services, Feathers provides instant CRUD functionality, it also can easily expose a RESTful and real-time API through HTTP/HTTPS and websockets.

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.

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.

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.
