This browser-based editor gives you a small space within your browser to try Sketchingpy. All of the files and data stay on your own computer so, if your machine fails or you clear your browser data, the sketchbook is lost. That said, you can save and load projects to files saved to your machine through export and import project. These files can be saved / backed up on other machines or shared! Finally, this small application also saves a copy of itself in your browser so you can run it even if you don't have access to the internet.
