Here you can try out some of CardStock's example stacks running on the web:
CardStock is inspired by the simplicity and power of Apple's old HyperCard programming tool. CardStock began as a desktop application for macOS, Windows, and Linux, but you can now also build, edit, and run CardStock stacks right here on cardstock.run. Just sign up for an account to begin! And if you prefer to design in the desktop application (Downloadable here), you can upload your stacks to cardstock.run from within the app, so they can be run in a web browser, and shared more easily.
