Koding vs CodeBunk

All languages, databases, and command-line tools are supported. Most machines are already set up with web project basics like Apache, PHP, MySQL, Ruby, Node.js, Perl, and Python and anything else can be installed via the SSH root access.

And link account to oDesk and Facebook.

Koding has a community feature that makes it easy to collaborate and share ideas with like minded developers all over the world. And the community itself is very active and helpful community.

Real-time code and terminal collaboration with integrated chat abilities.

With 256-color support.

Koding supports drag & drop, Dropbox, clone from Github, FTP and the ability to access them using SSH.

The Koding Package Manager (a successor to Apps) is command line tool for installing packages like nginx, Redis, VNC, Wordpress and many others. It consists of officially supported and user-built packages.

Ability to create different sized communities that can be public or private.

There's a built-in social network with developers from all over the world.

Unlimited user-defined domains and subdomains for private or shared VMs can be set up.

Koding uses the Ace editor that's developed by Cloud9. Besides the basics, it covers most important advanced code editor features such as code folding, converting cases, auto-completion, code analysis and refactoring, regex search and offers easy access to relevant documentation.

It also gives access to the CLI, has support for Vim and Emacs keybindings, includes multiple cursors and zen coding mode that removes all distractions and allows focusing on code.

Code execution works with all of the available languages and shows you the output on the side.

Over a dozen languages are supported for syntax highlighting and execution: Python, PHP, Ruby, Perl, Lua, Java, Clojure, Javascript, C, C++, Julia, Go, Erlang, Haskell.

It's possible to see how the code got written character by character with a feature called Code Playback. It allows reviewing the whole process in a condensed amount of time. Great for interviews to check how the interviewee got to the result.

REPL (read–eval–print loop) enables you to run commands interactively and test ideas out before committing them to code. CodeBunk has a dedicated space for REPL shells in the top-right corner of the interface so they can always be quickly accessed.

You can embed your code in your blog with CodeBunk. The embedded code is synced in realtime and is also runnable. All you have to do is add this to your post:

<div class="codebunk" id="[bunkid]" data-lang="[language]" data-runnable="[true|false]"></div>

CodeBunk has reserved a an area for text chat it the bottom-right corner and can start a video conference with all active members with one click.

Allows you to fork a session

Multiple users can belong to a Team and view bunks created in that team.

You can try the editor and code execution for free without, and get 5 free shared session try-outs when you sign up. Also, if you email team@codebunk.com for trial bunks, they do provide a bunch for free.
