Built entirely with Python, it provides a visual canvas-based workspace, flexible object editing tools, customizable canvas settings, seamless JSON generation, and much more.
One-click launch — simply run the Python script.
Zero external dependencies — requires only having Python 3.x installed.
Full working program — It may receive updates here and there, but it's a fully-functional full-featured release.
