Greenfoot is educational software for learning object-oriented programming with standard Java code. Learners build games, simulations, and other graphical programs by placing actors in worlds. The programming environment combines visualization and interaction tools with an IDE that includes project management, auto-completion, and syntax highlighting. Projects can be published online for others to play and comment on, and sharing is built into the environment. Greenfoot runs on Windows, macOS, and Linux; downloads cover Windows 10 and 11, macOS 11 and later, Ubuntu with Debian support, and a generic option for systems with JDK and JavaFX. From version 3.6.0, Intel/AMD systems need a 64-bit CPU and operating system; version 3.5.4 is the listed option for 32-bit support. The software is free, and its IDE source code is available under the GNU General Public Licence version 2 with classpath exception. Learning resources include written and video tutorials for beginners and advanced users, along with the Greenroom instructor community.
