Development Roadmap

Games made with GDevelop

Lil Bub

Lil BUB's HELLO EARTH is one of the many games built with GDevelop.


  • The Core library, the native and HTML5 game engines, the IDE, and all extensions (respectively Core, GDJS, newIDE and Extensions folders) are under the MIT license.
  • The name, GDevelop, and its logo are the exclusive property of Florian Rival.

Games exported with GDevelop are based on the HTML5 game engine (see Core and GDJS folders): this engine is distributed under the MIT license so that you can distribute, sell or do anything with the games you created with GDevelop. In particular, you are not forced to make your game open-source.
