Pros

Pro
Runs on top of Theano, TensorFlow or CNTK

You can choose the back-end for Keras. Simply change the backend field to "theano", "tensorflow", or "cntk".

Theano was discontinued in 2017, so TensorFlow or CNTK would be the better choice.

Pro
Simple to use

Pro
Can be used to write really short pieces of code

Keras enforces minimalism as much as possible. Because of this, it's possible to write a small Neural Network in just a couple of lines of code.

Pro
Really straightforward for someone who is familiar with deep learning

Pro
Quite modular

When using Keras you don't have to pull every part of the framework on your project. For example, you can only use training algorithms and not layer implementations. So it works more like a collection of libraries.

Cons

Con
Little customization compared to other frameworks

Keras is a high-level API. It's difficult to customize your model past a point. If you want to build something beyond the application-level, use Theano or TensorFlow. (Keras runs on top of either one of these anyways)
