Alternatives to GDevelop
Build games with a visual event system instead of writing all the logic as code. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
GDevelop
Build games with a visual event system instead of writing all the logic as code.
Replacements
Listings that take over the same core job as GDevelop.
Godot Engine
A 2D and 3D game engine that is completely free under the MIT licence, with no royalties and no revenue thresholds.
Godot is fully free under MIT with no hosted plan limits and supports 3D as well as 2D, but game logic is written in GDScript or C#.
GB Studio
Make Game Boy-style games with a visual editor.
GB Studio also uses a visual editor without conventional code, but projects must fit Game Boy graphics and gameplay constraints.
LOVE
Framework for making 2D games in Lua.
LOVE is a Zlib-licensed Lua framework for 2D games with no editor or scene tool, so all game logic is written as code.
Also worth comparing
These listings name GDevelop as their own alternative, so the relationship runs both ways.
Bitsy
Create small games and stories with a browser-based pixel-art editor.
GDevelop offers a visual event system and exports to several platforms, supporting larger games than Bitsy, though its hosted services have plan limits.
