CodeRun IDE: Free Web Based IDE For Developers
CodeRun IDE is a free web based IDE (Integrated Development Environment) tool for web developers, which enables you to create and deploy code-driven applications right from your browser.
It has lots of handy features like syntax coloring, code completion, debugging and testing, and supports C#/.NET, PHP, JavaScript, HTML and CSS. Database support includes SQL Server 2005 and Amazon SimpleDB.
You can either upload your existing code to test it online or start writing a new one. The files created can be organized into projects for better accessibility. The output console and error list window reports standard messages like errors, warnings and messages.

Additionally, you can let others debug your code by sharing it via unique URL. Anyone who navigates to that link will receive a separate, fully modifiable and runnable version of your code.
CodeRun is free to use, does not require installation of any extra software or plug-ins, and can be used as a replacement for your existing desktop IDE.
Note: CodeRun currently works on Google Chrome and Internet Explorer.
Features:
- Develop, debug and deploy web applications right from your browser.

Considering its web based natire, I wonder if it is as convenient and fast as a desktop equivalent…
Tried it out and its actually amazingly fast! Auto complete and code coloring works like a charm. I’m surely going to look deeper into that one.
