MooShell is an web application that allows you to test your JavaScript, HTML and CSS in relevant fields and run to see the output. You can save your code for further usage and to share with others via a unique URL. It provides you with an update option to create a new version of your existing code. To choose the MooTools version, you can use the settings panel in the sidebar. MooShell can come handy for programmers and web developers to quickly and easily test and debug code snippets before actually implementing them. The web application is also light weight, free for use and does not require installation of any extra software.
