Plug-in the services you already know!

We've all spent a lot of time and effort to become the coders that we are today. This makes us passionate about the choices we've made when choosing our tools. Cloud9 IDE is a flexible system that integrates with many other services that are important to the development lifecycle. And, since the editor is open-source, you can feel free to write your own extension to connect to any web-based platform.
