People already do to some extent. That article mentions one example, the Trello clone (frontend?), but there are others like in this Reddit article: https://www.reddit.com/r/godot/comments/a809ij/godot_for_application_development/ https://www.reddit.com/r/godot/comments/a809ij/godot_for_app... * The Godot editor itself: https://docs.godotengine.org/en/stable/getting_started/step_by_step/godot_design_philosophy.html#the-godot-editor-is-a-godot-game https://docs.godotengine.org/en/stable/getting_started/step_... * GUI Toolkit: https://github.com/Quark-Toolkit/Quark https://github.com/Quark-Toolkit/Quark * Pixel art editor: https://www.orama-interactive.com/pixelorama https://www.orama-interactive.com/pixelorama * Particle effects editor: https://benhickling.itch.io/blastfx https://benhickling.itch.io/blastfx * RPG builder: https://www.rpginabox.com/overview/ https://www.rpginabox.com/overview/ * Fantasy map editor: https://www.wonderdraft.net/ https://www.wonderdraft.net/ * Brainfuck IDE: https://github.com/wmww/BrainfuckIDE https://github.com/wmww/BrainfuckIDE * 3D presentation editor: https://github.com/janparkio/3d-presentation-godotengine https://github.com/janparkio/3d-presentation-godotengine I've looked in to this myself and noted the following: * It's easy to compile out features you don't want (3D, physics, etc.): https://docs.godotengine.org/en/stable/development/compiling/optimizing_for_size.html https://docs.godotengine.org/en/stable/development/compiling... * While Godot has a small file size, it's Hello World memory usage is ~300MB, which I think is even more than a Hello World in Electron (perhaps fixable by removing features) * There is a setting to stop UI updates when the window loses focus which means it doesn't chomp CPU/GPU while not in use
