Why CST?


CST has a basic syntax and is very easy to learn. Start off on the right foot by checking out our docs.


CST implements commands that can perform complex tasks at your fingertips. Pack power into every command using arrays, storage, files, and file execution.


From data handling to tab managing, CST can do anything along the way. With the ability to run external languages such as HTML, CSS, and JavaScript, the possibilities are limitless.
