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.
