PlayCanvas vs Babylon.js
Same catalog, two overlapping tools. Catch and verdict side by side. No winner score.
PlayCanvas
MIT WebGL2/WebGPU engine plus an optional hosted Editor
Freemium · freemium
The Catch
Do not conflate the MIT engine with the hosted Editor. Private cloud projects are the paid line (Personal 15 USD/month; Organization 50 USD per seat/month). Cancel and private projects lock until you resubscribe or make them public.
Verdict
OSS engine, optional Editor. Public projects are free; private cloud is not.
Babylon.js
Apache-2.0 3D engine for the web, now on v9
Apache-2.0 · open-source
The Catch
Heavier than a 2D starter. docs.babylonjs.com (with an s) has returned 500; working docs host is doc.babylonjs.com. Editor pricing was not verified here, so it is omitted.
Verdict
The open 3D game and rendering engine for the web. Apache-2.0, on v9.
