PlayCanvas vs. Spatial.io

Q: How does Needle Engine compare to PlayCanvas?

PlayCanvas is an all-in-one, browser-based engine and editor with its own proprietary runtime. Needle Engine instead integrates with desktop editors (Unity, Blender) and a three.js-based runtime, focusing on glTF, automatic optimization and easy embedding into existing web stacks via npm and web components. Pick PlayCanvas for a self-contained web platform; pick Needle to reuse Unity/Blender skills and integrate 3D into larger web apps.

	Web-first runtime integrated with Unity and Blender plugins, complemented by Needle Cloud for optimization and hosting. Needle	Combines an open-source engine with a proprietary cloud-based visual editor focused on collaborative game and interactive web app development.
