This project began as a fork of Joyent's Node.js and is compatible with the npm ecosystem. On the other hand, Symfony is detailed as "A PHP full-stack web framework". Symfony is written with speed and flexibility in mind. It allows developers to build better and easy to maintain websites with PHP. Symfony can be used to develop all kind of websites, from your personal blog to high traffic ones like Dailymotion or Yahoo! Answers.
