Welcome to WatermelonKatana

Post your projects, interact with other people's projects, chat with your friends, and more! We have a large gallery of games and a growing user base. Help us out by either posting your browser game here or playing other people's games!


On WatermelonKatana you can publish old code.org projects including gamelab, spritelab, and applab. You can also publish Khan Academy projects, Scratch projects, and urls to any self-hosted projects. This site was created as a third-party replacement for code.org's public project section. View our extensive curated gallery of code.org games and projects! We also have a custom Turbowarp engine for code.org, allowing your projects to run orders of magnitude faster. Our forum is a place for those new at programming to recieve help from those experienced at it.


WatermelonKatana was created by a group of passionate programmers from the code.org community. We are dedicated to providing a safe and well-moderated website to allow fledgling developers to share, remix, and get feedback on their projects. (PS: If you are code.org staff reading this, we would love to collaborate with you to provide a safe way to share code.org projects to the web.)
