What each one is
PlayCanvas
PlayCanvas Engine is an open-source JavaScript engine for building interactive 3D and 2D apps, games and visualizations that run in a web browser. It is distributed as the npm package playcanvas and includes features such as rendering, physics via ammo.js, animation, input, 3D sound, WebXR support and glTF asset loading.
three.js
Three.js is a JavaScript library that lets developers create 3D scenes, cameras, and objects and display them in a web page. The README describes its aim as an easy-to-use, lightweight, cross-browser, general-purpose 3D library. It currently includes WebGL and WebGPU renderers, with SVG and CSS3D renderers available as addons.

Strengths
PlayCanvas
- Free and open source under the MIT license
- Built on modern browser graphics APIs (WebGL2 and WebGPU) and supports glTF 2.0
- Installs with a single npm command and includes a scaffolding CLI for full projects
three.js
- The README presents it as a general-purpose, cross-browser 3D library
- Includes a documented usage example that creates a scene, camera, mesh, and renderer
- Has extensive official resources listed, including examples, docs, and a manual
Not ideal for
PlayCanvas
- People who want a visual, no-code tool only: the README describes the browser-based Editor as a separate project
- Beginners with no JavaScript experience, since the README's examples assume familiarity with JavaScript modules and npm
- Projects that need a native desktop or console build, which the README does not mention
three.js
- People who only need 2D graphics, since the library is focused on 3D scenes
- Anyone looking for a finished app rather than a code library to build with
- Beginners with no JavaScript experience, as the README code assumes familiarity with modules and the browser
Trade-offs
PlayCanvas
- The README is truncated and gives little detail on browser or device support
- Requires JavaScript or TypeScript knowledge to use the engine directly
- Learning the engine's API and scene model takes time; the README points to external manuals for depth
three.js
- The full git history is about 2 GB, so a shallow clone is recommended for most users
- The README does not describe install steps beyond the import example, so setup details must come from the docs
- Working in 3D requires understanding concepts like cameras, geometry, and materials
