GDevelop: Build 2D, 3D, and Multiplayer Games Without Code

Overview

GDevelop is a game development editor and engine for making 2D, 3D, and multiplayer games for mobile, desktop, and the web. Its visual, event-based workflow is designed to let people create game logic without writing code, while extensions and engine internals also provide options for developers.

The project combines an editor, a game engine, built-in extensions, and related services. It makes sense for creators who want one tool for designing a game and exporting it to multiple platforms, rather than assembling a game framework from separate libraries.

Key Features

• Visual event-based logic for building game behavior without code.
• Support for 2D and 3D rendering through PixiJS and Three.js.
• Multiplayer game development support.
• Modular behaviors and extensions for adding objects and engine features.
• Export targets include mobile, desktop, and the web.
• React and Electron-based editor, with an engine written in TypeScript.
• WebAssembly bindings and physics extensions, including Box2D and Jolt Physics for 3D.

Use Cases

• A first-time game creator can prototype a 2D game using visual events instead of learning a programming language first.
• An indie developer can build a 2D or 3D game and target web, desktop, or mobile releases from the same tool.
• A small team can use modular behaviors and extensions to add game features without maintaining every engine component themselves.
• A JavaScript or TypeScript developer can contribute to the editor, engine, or extensions, or create extensions for specialized game needs.

Getting Started

Download the app from the GDevelop homepage. For editor or engine development, follow the contributor README; the repository README links to the documentation for further guidance.

License in Plain Words

No standard license was detected. Without a license, the default copyright rules apply: you may read the code, but not reuse it. Check the repository or ask the authors.

Alternatives

• OpenRA: OpenRA is focused on building and playing real-time strategy games, rather than creating games across genres with visual events.
• flame: Flame is a code-first Dart engine for 2D games built with Flutter, rather than a visual, cross-platform editor with 2D and 3D tools.

Considerations

GDevelop covers a wide area, from a visual editor to a game engine and extensions, so teams should confirm that its workflow and available extensions meet their particular production needs. The project is active, with regular commits and releases and a broad contributor base; its issue queue is substantial, so do not assume every reported problem will receive prompt attention. The README states that the core library, engines, IDE, and extensions are MIT-licensed, while the project name and logo are reserved. The GitHub metadata reports the repository license as NOASSERTION, so review the relevant license files and branding terms for your intended use.
