Collaborvation

It’s finally here. Experience the awesome productivity of coding together — no matter where you are. Cloud9 IDE now enables developers around the world to edit the same code and chat together in real-time. Developers can pair program, review code, get an audience involved, or teach a group of students the art of programming.

The way you code together will never be the same again.

C9 Cloud Your Workspace in the Cloud, vvwith SSH and FTP.

This is the platform professional developers have been waiting for. Your Workspace in the Cloud gives every developer the raw power of their own runtime environment. Run your Python and Ruby apps. Compile with gcc. You even get a true terminal with the Unix commands you love — like make, telnet and VIM.

For developers with their own servers, there’s Cloud9+SSH. Now you get the same amazing Cloud9 experience — including collaboration — attached to the server you already own. Keep your code where it is, and Cloud9 will bring it all together.

You can even connect to your FTP servers and use Cloud9 to see your file tree, drag-n-drop files and edit your code. Working with WordPress and Drupal has never been this convenient.

Code Completion So you can focus on the big picture.

Cloud9 brings the depth and sophistication of JavaScript analysis, right to your browser. As you type, code suggestions appear below your code. Hovering over suggestions shows helpful JavaScript and Node.js documentation, so you always know what you’re working with.

App Deploy Give your application an audience.

Cloud9 offers incredible choices for bringing your application to life: Heroku, Cloud Foundry and Windows Azure. It is the easiest and quickest path to getting your application online.

Round out your development process with multiple server targets: alpha, beta, staging, and production.

The Cloud9 Experience

Search
The search UI has been completely reworked. Even regex searches are more expressive. Highlighting and syntax hints let you know when you're on the right path, or if you're missing an operator.
Goto File
Insanely fast file access means you’re always milliseconds away from opening the right file.
Adaptive Themes
Now Cloud9 updates its skin to match your editor theme. Try hovering over themes to see instant previews before choosing the perfect one

The Awesome Editor

Code Folding
When you need to focus on important functions, code folding collapses everything else so it’s out of your way. Folding arrows appear when your mouse hovers over the line numbers, then fade when you go back to coding. There when you need them, gone when you don’t.
Multiple cursors
You’ve never seen multiple cursors like this. Keyboard shortcuts connect you to a ton of useful functions: search for some text and then add cursors to results; add a cursor to the rows above and below the current line; or, simply type or paste onto multiple cursors.
Focus
Free your editor to its full potential. Every part of the Cloud9 UI can be collapsed or hidden entirely, so you get the maximum space to focus on your code. And for the truly exceptional among us, there’s zen mode, where the editor floats above the IDE to fill 100% of the browser.

Drag & Drop

The project tree scrolls, highlights and expands folders automatically for the most natural drag n drop experience.

You can even drop files onto your FTP server.

Git & Mercurial support

Version control is essential to every codebase. That’s why git and mercurial are baked into every aspect of your Cloud9 project, from creation to the command-line.

Run git and hg commands in the command-line, just like you would on your local terminal.

Git blame your files to see who introduced that bug you’ve been tracking down.

Command-Line

The command-line is your shortcut to a ton of useful features, like "mkdir", "npm", "git" and "zen".
And now, the command-line runs NPM packages.
For example, you can “npm install express” and then enter “express” to scaffold your express app. If the NPM package has a stdin prompt like “coffee”, the command-line handles that too.
