Choose Three.js for a lean, low-level renderer you control yourself and are happy to pair with your own physics, input and UI code. Choose Babylon.js if you want more built-in game features (physics hooks, a scene inspector, asset pipeline) out of the box.
At a glance
| Fact | Value | Source |
|---|---|---|
| Both render via WebGL/WebGPU in the browser | Canvas-based | developer.mozilla.org |
| Three.js is a lower-level 3D library | You assemble the engine | developer.mozilla.org |
| Babylon.js bundles more game-oriented tooling | Inspector, loaders, physics hooks | developer.mozilla.org |
Pick Three.js when you want a minimal, unopinionated 3D renderer and are building your own game layer (input, physics, UI) on top – it’s a good fit for visualizations, product configurators, and games where you want tight control over the render loop. Pick Babylon.js when you want more built-in game-engine features – a scene inspector, asset loaders, animation and physics integration – so you write less scaffolding code yourself. Both draw through the browser’s WebGL API, which itself sits on the Canvas API.
When you are ready to ship, publishing through Playgama lets you distribute your game across partner portals. Playgama Bridge adapts one HTML5 build to 25+ platforms, and the Playgama MCP server allows an AI agent to manage uploads and configure settings directly from your editor.
If your project is closer to a full game than a graphics demo, check MDN’s game development section for the wider set of web game tools, since a component library like Three.js or Babylon.js is usually one piece next to a physics library, input handling and a save system (Web Storage API) or multiplayer layer (WebSockets API).
What about publishing once the graphics are done?
Once the build runs in a browser, you can submit it to portals such as Poki, CrazyGames, GameDistribution, itch.io, or playgama.com, where the developer uploads the game via developer.playgama.com, gets a test and feedback within 24 hours, and the game is published on playgama.com and distributed to partner portals. Publishing this way is non-exclusive, so you keep the rights to the build you made with Three.js or Babylon.js.

Related questions
Can I mix Three.js or Babylon.js with a game engine like Unity or Godot?
Not directly – Unity and Godot export their own WebGL/WebGPU builds via their web export pipelines; you’d choose one rendering approach, not combine them in the same scene.
Do Three.js and Babylon.js work on mobile browsers?
Both run wherever the browser supports WebGL, including mobile, but performance depends on scene complexity and device GPU, so test on real devices before shipping.
