Both are free engines with a built-in editor and no royalties. Godot is MIT-licensed with GDScript and C#; Defold is source-available with Lua and is known for very small builds.

- License: Godot — MIT — open source, no fees at any revenue; Defold — Defold License — free with source available, but not OSI open source: you can't commercialise the engine or editor itself
- Language: Godot — GDScript, plus C#; Defold — Lua, with optional typed Lua through Teal
- Web export: Godot — WebAssembly and WebGL 2; Godot 4 can't export C# projects to the web; single-threaded by default since 4.3; Defold — WebAssembly HTML5 bundles; Defold publishes about 0.83 MB for an empty Wasm project with Brotli
- Consoles: Godot — Through third-party porting partners; Defold — Possible, but needs platform access and extra setup

Pick Godot when:
- You want an MIT-licensed engine and a larger scope, including 3D
- You prefer GDScript's Python-like syntax or want C# on desktop and mobile

Pick Defold when:
- Download size and startup time matter, as with web, mobile, and playable games
- You like Lua and a lean, component-based project structure

Bottom line: Godot for breadth and a permissive license, Defold for small builds and Lua. Both cost nothing to ship with, so the deciding factors are language and target size.
