Router is the best part which I have extensively used for rest apis

Is a fast framework, made to create high performance applications.

Personally I like this framework the best. Much like in life, a big challenge in programming is keeping a good balance between order and freedom. This framework is very well balanced in this respect. Basically if you're a cool, easy-going and fun individual, this framework is made in your style. It is light, fast, minimal, flexible, intuitive, good for projects of all sizes, and is stable yet growing quickly. Is it new and missing some trivial things? Yes. Can those things be fixed with a little effort? Yes. Another awesome thing about Phalcon is Zephir. With it you can now write PHP extensions pretty much in PHP (used to be in C). Phalcon itself is written in Zephir. So, this isn't just another competing framework but an effort at something bigger and I think that is important to consider too.
