The types of applications developed by Cold Fusion can be fairly sophisticated, and the HTML page metaphor will be easy for Webmasters and HTML experts to understand. Cold Fusion extends HTML though the definition and use of a proprietary tag language called the Cold Fusion Markup Language, similar to Microsoft's Active Server Page technology. Cold Fusion's development environment is based on the HomeSite HTML editor, which is built for rapid development. However, it lacks integrated debugging capabilities. The development environment leverages any existing HTML programming skills your organization may have.
Users can also develop their own palettes of custom tags.
