CodeRun Studio is a free, cross-platform Integrated Development Environment (IDE), designed for the cloud. It enables you to easily develop, debug and deploy web applications using your browser. CodeRun Studio can be used instead or alongside your existing desktop IDE. You can upload existing code in order to test it in the cloud or for sharing with your peers.

CodeRun features native support for C#/.NET (3.5), PHP (5.1), JavaScript, HTML and CSS. C# support includes ASP.NET, WCF, Silverlight and WPF browser application development and deployment. Database support includes SQL Server 2005 and Amazon SimpleDB. This means you do not have to learn anything new in order to begin working with CodeRun. Simply upload you existing code, or start from one of the built-in templates.
