This is your Workspace
We maintain it, you control it

Fast. Scalable.
Easily handle hundreds of thousands of files in your workspace and hundreds of thousands of lines of code in the editor
Powerful Workspaces
Set up your system without any hassle
Simply pick your configuration and develop your app. No need to spend valuable development time on system setup and maintenance. You can create, build and run any development stack in seconds. We maintain it, you control it.
All the freedom you’d expect
Workspaces are powered by Docker Ubuntu containers that give you full freedom over your environment, including sudo rights. Do a git push, compile SASS, see server output, and Run apps easily with the built-in Terminal and Runners.

Awesome features
Built-In Terminal
For command-line wizardry
Run any powerful command on your Ubuntu workspace or on your own VM.
Do a git push, compile your app, or tail server output - the Terminal enables any development stack.
Language Tools
Make writing code a breeze
Code Completion suggestions appear as you type to help you code faster and avoid typos. Use the Outline view to better understand your code, and Jump to Definition of variables for easy navigation.
Debugger
Inspect the state of your app
The Debugger enables you to set breakpoints, step over and through, and inspect variables of any JS/Node.js app. Or jump right in to the Immediate Window to execute code in a debugging session.
Split View
Configure your own UI
Simply drag any file or Terminal tab around to create as many split views as you like, in any direction. In fact, every part of the UI can be enabled/disabled to your liking.
Themes
Make Cloud9 more awesome
Choose from 30+ themes and color schemes that control syntax highlighting and the UI. You can also custom style Cloud9 by editing your stylesheet.
Run Panel
Run any language
Choose from an extensive set of default Runners to execute your app, such as Ruby, Python, PHP/Apache, CoffeeScript, or Node.js. Or run any command in a Run config, including environment variables.
Key Bindings Editor
Muscle-memory FTW!
All keyboard commands can be fully configured, so you don't have to learn a new set of keystrokes. Or simply import a keymap file from a friend. It's like you never switched tools.
VIM/Emacs/Sublime Mode
Old school meets new school
Used to VIM, Emacs, or Sublime? Simply configure Cloud9 to go into one of these modes to get the best of both worlds.
Built-In Image Editor
Looks are everything
Why interrupt your web development flow to edit an image on your machine? Cloud9 also sports an image editor. Resize, crop, rotate, or flip - straight from the browser.
