Three.js is a low-level 3D rendering library you code against directly; Babylon.js is a fuller game-oriented framework with built-in physics, audio, and scene tools; PlayCanvas adds a visual editor and hosted workflow on top of a WebGL/WebGPU engine. Pick based on how much you want to build yourself.
At a glance
| Fact | Value | Source |
|---|---|---|
| Three.js scope | Rendering library, code-first | developer.mozilla.org |
| Babylon.js scope | Full game framework, code-first | developer.mozilla.org |
| PlayCanvas scope | Engine plus visual editor | developer.mozilla.org |
All three run 3D in the browser via WebGL (and increasingly WebGPU), but they sit at different levels. Three.js is a rendering library: you write JavaScript, build your own scene graph, and wire up loaders, controls, and game logic yourself – most flexible, least structure. Babylon.js is a step up: it bundles physics, audio, animation, a node material editor, and scene management, so you write less glue code for a full game. PlayCanvas pairs a similar engine core with a hosted visual editor where you assemble scenes, scripts, and assets in a browser UI, which suits teams that want non-programmers involved or a faster iteration loop.
When you are ready to distribute, publishing through Playgama lets you reach 100+ partner platforms using the open-source Playgama Bridge SDK.
Which one should you use?
- Three.js – custom renderers, data visualizations, or when you want full control and are comfortable building your own game layer.
- Babylon.js – full 3D games where you want physics, animation, and scene tools included rather than assembled from libraries.
- PlayCanvas – projects that benefit from a visual editor and shared project workspace, especially with non-coder collaborators.
All three export to standard HTML5/WebGL builds, so once your game runs in a browser tab, the publishing step is the same regardless of which one you used: test performance (see Core Web Vitals), then submit to portals. Options include Poki, CrazyGames, GameDistribution, itch.io, and playgama.com, where you upload via the Developer Console at developer.playgama.com and get test feedback before the game goes live on the portal and its partner network.

Related questions
Can I switch from Three.js to Babylon.js later?
Not directly – they have different APIs and scene models, so switching means rewriting rendering and game code, not just swapping a library reference.
Do these libraries work with Unity or Godot web builds?
No, they are separate from engine exports. Unity WebGL and Godot web builds ship compiled engine code; Three.js, Babylon.js, and PlayCanvas are used directly in JavaScript projects.
Which is easiest for someone who can’t code much?
PlayCanvas, since its visual editor lets you build scenes and hook up basic logic with less hand-written JavaScript than Three.js or Babylon.js.
