What's Good
MIT. Full 2D/3D engine, editor, GDScript/C#. HTML5/Wasm + WebGL2 export. Forever free, no royalty. Huge asset and learning ecosystem.
The Catch
Loud: Compatibility/WebGL2 only for web; threaded export needs COOP/COEP — single-thread default since 4.3 for embeds. Not Phaser JS canvas. Distinct from Phaser.
Verdict
MIT Godot. Web works in Compatibility/WebGL2; plan COOP/COEP only if you need threads.
