I really like Phalcon, but I don't like over 50 not reviewed pull requests (you need to check yourself if something has already been fixed and hangs in PR), lots of not closed issues, insistence on backward compatibility, the process of releasing version. I contributed with phalcon 2.0 cphalcon/mruz's pulls and I really like Zephir.
I needed to create a simple and fast app for own use, but I decided to make small framework and make it public. Framework written from scratch, some components work like in Phalcon.
