CodeDam
CodeDam is a free visual coding playground for children, parents, and teachers.
What CodeDam is
CodeDam is a free visual coding playground for children, parents, and teachers. It runs in a browser on a laptop or tablet and works with mouse, keyboard, or touch, with no download or account required to begin. In the Workshop, learners connect drag-and-drop blocks for variables, mathematics, conditions, loops, and other concepts. Programs can be run and stepped through so each block’s behavior is visible. As blocks are assembled, matching JavaScript or Python code updates in real time, linking visual construction with written programming languages. Users can save and load projects and download them for later use. CodeDam supports project-based learning and computer science topics. Its Free plan costs nothing and includes the visual block-coding playground, JavaScript and Python previews, and project saving and downloading. The project is independently operated and says it is not a registered charity or nonprofit.
