Cloud9 combines a powerful online code editor with a full Ubuntu workspace in the cloud. Cloud9 gives developers the power of an IDE with the freedom and flexibility of the cloud. Write, run, and debug your code with our powerful and flexible cloud IDE. Collaborate on your workspaces publicly, or keep it private. The choice is yours!

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.

• Free yourself from your machine – Cloud9 gives you the freedom of the cloud. 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.

Or connect Cloud9 to your own VM via SSH

• See each other type – Code together in real time
• You control what you share – Share your IDE, your workspace, a preview, or your running app
• Never lose a line of code – Replay all edits and see your code at any point in time

The coolest of the cool features

• Preview in any browser – Say goodbye to installing browsers and platforms in virtual machines for compatibility testing. Live Preview enables you to interactively see what your web application looks like in any browser! Just choose one of the 300+ browser/OS platform combinations.

• 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 to 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 inspects 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 lets you 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 your workspace even 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 with 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 uses 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 is where 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 - 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.
