I know what you’re thinking: why on Earth would you use JavaScript to develop games? I thought the same thing when I discovered that you could use JavaScript and HTML5 to develop 3D games. The truth is, since the introduction of the JavaScript WebGL API, modern browsers have intuitive capabilities that enable them to render more complex and sophisticated 2D and 3D graphics without relying on third-party plugins.
You could start your web game development journey with pure JavaScript, which is probably the best way to learn if you’re a beginner. But why reinvent the wheel when there are so many widely adopted game engines to choose from?
If you didn’t know, an HTML5 game engine is a software framework designed to help you build browser-based games with HTML5 technologies, primarily JavaScript, along with HTML and CSS. Most HTML5 game engines are built for running directly in modern web browsers without the need for plugins, This makes them ideal for creating cross-platform, mobile-friendly experiences.
This guide ranks the top 10 JavaScript/HTML5 game engines by popularity, capability, and use case. Whether you’re a solo indie developer, mobile-focused creator, rapid prototyper, or part of a small team, there’s something here for you. These engines power everything from lightweight browser games to full-featured cross-platform apps.
We’ll highlight each engine’s strengths, learning curve, and ideal scenarios—plus provide an easy-to-follow demo (web-based) to get you started.
We’ll cover:
Editor’s note: This article was updated by Saleh Mubashar in May 2025 to cover four additional HTML5 game engines: GDevelop, Defold, Godot Web Build, and Construct.
Before we start, here are a few important factors to consider when selecting a JavaScript/HTML5 game engine. The right choice depends on your project type, experience level, and deployment goals:
Decide whether your game will be 2D, 3D, or a mix. Some engines (like Pixi.js) are built for 2D, while others (like Three.js or Babylon.js) excel at 3D rendering.
Engines like Phaser and Construct are beginner-friendly, while others may require solid JavaScript or game dev experience.
Some engines come with visual editors or online sandboxes that help speed up development (e.g., Godot Web, PlayCanvas, Construct), while others are code-only.
If you’re targeting mobile browsers or devices, performance is key. While all modern engines support mobile browsers, solutions like Phaser with Cordova or Defold’s native export options provide better performance for app store distribution. With web-only engines, a lot of tedious optimization is needed, especially for lower-end devices.
Licensing affects what you can build and publish. Most engines in this guide are open source (MIT, Apache), but others, like Construct, use a freemium model that may limit commercial use without a paid plan. Make sure the license works for your use case.
Popular engines like Phaser, Three.js, and Babylon have large, active communities, frequent updates, extensive tutorials, GitHub repositories, and Stack Overflow threads. On the other hand, newer or more niche engines may offer unique features but might lack community support, making them harder to work with for solo developers or beginners.
To help you decide faster, here’s a side-by-side comparison of the top engines based on the criteria above:
| Engine | Type | License / Cost | Mobile Support | Editor Support | Community & Resources |

Three.js is one of the most popular JavaScript libraries for creating and animating 3D computer graphics in a web browser using WebGL. It’s also a great tool for creating 3D games for web browsers.
Because Three.js is based on JavaScript, it’s relatively easy to add any interactivity between 3D objects and user interfaces, such as keyboard and mouse. This makes the library perfectly suitable for making 3D games on the web.
If you’re looking to delve into creating simple or complex 3D objects on the web, Three.js is the go-to library. Its top advantages include a vast community of talented users and abundant examples and resources.
Three.js is the first 3D animated library I worked with, and I’d recommend it to anyone starting out with game development.
Let’s create a simple rotating geometry to demonstrate what Three.js can do:
import * as THREE from 'js/three.module.js'; var camera, scene, renderer; var geometry, material, mesh; animate();
Create an init function to set up everything we need to run our demo animation with Three.js:
Learn more →function init() {
const camera = new THREE.PerspectiveCamera( 60, window.innerWidth / window.innerHeight, .01, 20 );
camera.position.z = 1;
const scene = new THREE.Scene();
const geometry = new THREE.BoxGeometry( 0.5, 0.5, 0.5 );
const material = new THREE.MeshNormalMaterial();
const mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
const renderer = new THREE.WebGLRenderer( { antialias: true } );
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
}
Next, create an animate function to animate the object with your desired motion type:
function animate() {
init();
requestAnimationFrame( animate );
mesh.rotation.x += .01;
mesh.rotation.y += .02;
renderer.render( scene, camera );
}
The finished result should look like this:
Refer to the repo and official documentation to learn more about Three.js.
If you’re looking for a JS library to create rich and interactive 2D graphics with support for cross-platform applications, look no further than Pixi.js. This HTML5 creation engine enables you to develop animations and games without prior knowledge of the WebGL API.
Pixi is a strong choice in most scenarios, especially if you’re creating performance-oriented 3D interactive graphics with device compatibility in mind. Pixi’s support for Canvas fallback in cases where WebGL fails is a particularly enticing feature.
Let’s build a simple demo to see Pixi.js in action. Use the following command to add Pixi.js to your project:
npm install pixi.js
Or CDN:
<script src="https://cdnjs.cloudflare.com/ajax/libs/pixi.js/5.1.3/pixi.min.js" ></script>
Create a script file and add the following code:
import * as PIXI from 'pixi.js';
const app = new PIXI.Application();
document.body.appendChild(app.view);
app.loader.add('jumper', 'jumper.png').load((loader, resources) => {
const bunny = new PIXI.Sprite(resources.bunny.texture);
bunny.x = app.renderer.width / 2;
bunny.y = app.renderer.height / 2;
bunny.anchor.x = .5;
bunny.anchor.y = .5;
app.stage.addChild(bunny);
app.ticker.add(() => {
bunny.rotation += .01;
});
});
The result should look something like this:
Refer to the repo and official documentation to learn more about Pixi.js.
Phaser is a cross-platform game engine that enables you to create JavaScript and HTML5-based games and compile them for many platforms. For example, you might decide to compile your game to iOS, Android, and other native apps using third-party tools.
Phaser 4 is a full rewrite (smaller bundle, modern TypeScript, WebGPU focus) and is currently in beta. It is expected to be released at the end of 2025.
Phaser is good for developing cross-platform game applications. Its support for a wide range of plugins and the large community of developers building games with Phaser make it easy to get started with the framework.
Let’s build a basic application with Phaser. First, install Phaser as a Node module or via CDN:
npm install phaser
OR:
<script src="//cdn.jsdelivr.net/npm/[email protected]/dist/phaser.min.js"></script>
Next, pass in some default configurations to your Phaser engine:
const config = {
type: Phaser.AUTO,
width: 800,
height: 600,
physics: {
default: "arcade",
arcade: {
gravity: { y: 200 },
},
},
scene: {
preload: preload,
create: create,
},
};
const game = new Phaser.Game(config);
Create a preload function to load in your default static files:
function preload() {
this.load.setBaseURL("https://labs.phaser.io");
this.load.image("sky", "assets/skies/space3.png");
this.load.image("plane", "assets/sprites/ww2plane.png");
this.load.image("green", "assets/particles/green.png");
this.load.image("astroid", "assets/games/asteroids/asteroid1.png");
this.load.image("astroid2", "assets/games/asteroids/asteroid1.png");
this.load.image("astroid3", "assets/games/asteroids/asteroid1.png");
}
Finally, define a create function to display your newly created game:
function create() {
this.add.image(400, 300, "sky");
this.add.image(700, 300, "astroid");
this.add.image(100, 200, "astroid2");
this.add.image(400, 40, "astroid3");
const particles = this.add.particles("green");
const emitter = particles.createEmitter({
speed: 100,
scale: { start: 1, end: 0 },
blendMode: "ADD",
});
const plane = this.physics.add.image(400, 100, "plane");
plane.setVelocity(100, 200);
plane.setBounce(1, 1);
plane.setCollideWorldBounds(true);
emitter.startFollow(plane);
}
Refer to the repo and official documentation to learn more about Phaser.js.
Babylon.js is a powerful, simple, open game and rendering engine packed into a friendly JavaScript framework.
Many large brands trust Babylon.js as their game development engine of choice. The Babylon Playground, a thriving hub of code samples, is a great tool to help you get started with the framework.
Babylon and its modules are published on npm. To install it, run the following command in your command line tool:
npm install babylonjs --save
Alternatively, you can integrate the library into your project via CDN. To do so, create an index.html file and add the following code:
<canvas id="renderCanvas"></canvas> <script src="https://cdn.babylonjs.com/babylon.js"></script> <script src="script.js"></script>
After installation, you can start using the library by importing the global object or destructuring the scene and engine methods like so:
import * as BABYLON from 'babylonjs'
// OR
import { Scene, Engine } from 'babylonjs'
Next, create a script.js file and include the following code:
const { createScene } = require('scene.js')
window.addEventListener('DOMContentLoaded', function(){
const canvas = document.getElementById('renderCanvas');
const engine = new BABYLON.Engine(canvas, true);
const scene = createScene();
engine.runRenderLoop(function(){
scene.render();
});
window.addEventListener('resize', function(){
engine.resize();
});
});
Create a scene.js file and add the following code:
export function(){
const scene = new BABYLON.Scene(engine);
const camera = new BABYLON.FreeCamera('camera', new BABYLON.Vector3(0, 5,-10), scene);
camera.setTarget(BABYLON.Vector3.Zero());
camera.attachControl(canvas, false);
const light = new BABYLON.HemisphericLight('light', new BABYLON.Vector3(0,1,0), scene);
const sphere = BABYLON.Mesh.CreateSphere('sphere', 16, 2, scene);
sphere.position.y = 1;
const ground = BABYLON.Mesh.CreateGround('ground', 6, 6, 2, scene);
return scene;
}
Below is a preview of what your animation should look like:
Refer to the repo and official documentation to learn more about Babylon.js.
Matter.js is a JavaScript 2D, rigid-body physics engine for the web. Even though it’s a JavaScript physics engine, you can combine it with various packages and plugins to create interesting web games.
Matter.js is subjectively the best library for creating simple, moving animation objects. Matter.js is a physics library that focuses more on 2D objects. However, you can combine it with third-party solutions to create dynamic games.
To get started with Matter.js in a vanilla project, download the matter.js or matter.min.js package file from the official GitHub repo and add it to the HTML file with the following code:
<script src="matter.js"></script>
However, if you’re using a bundler, such as Parcel, you can install the package as a Node module via npm or yarn using the following commands:
npm install matter-js //OR yarn add matter-js
The following is a minimal example using the built-in renderer and runner to get you started:
// module aliases
const Engine = Matter.Engine;
const Render = Matter.Render;
const World = Matter.World;
const Bodies = Matter.Bodies;
// create an engine
const engine = Engine.create();
// instantiating the renderer
const render = Render.create({
element: document.body,
engine: engine,
options: {
wireframes: false,
showAngleIndicator: false,
background: "white",
},
});
// create two boxes and a ground
const boxA = Bodies.rectangle(300, 300, 70, 70);
const boxB = Bodies.rectangle(400, 10, 60, 60);
const ground = Bodies.rectangle(300, 510, 910, 10, { isStatic: true });
// add all bodies to the world
World.add(engine.world, [boxA, boxB, ground]);
// run the engine
Matter.Runner.run(engine);
// run the renderer
Render.run(render);
Include the above script in a page that has Matter.js installed, and then open the page in your browser. Ensure the script is at the bottom of the page (or called on the window load event or after the DOM is ready).
You should see two rectangular bodies fall and then hit each other as they land on the ground. If you don’t, check the browser console to see if there are any errors:
Refer to the repo and official documentation to learn more about Matter.js.
PlayCanvas uses HTML5 and WebGL to run games and other interactive 3D content in any mobile or desktop browser. Though it’s free and open sourced, PlayCanvas focuses more on the game engine than the rendering engine. Therefore, it’s more suitable for creating
3D games that use WebGL and HTML5 Canvas.
PlayCanvas is great for creating small public projects or school projects — at least, that’s what I’ve used it for. If you need more features and more control over your game development, you might want to consider subscribing for premium features.
For now, let’s do some basic rendering with the engine. As a first step, download the package file from the GitHub repository and add it to your project using the following code:
<script src='https://code.playcanvas.com/playcanvas-stable.min.js'>
Next, create a script.js file and link it to the HTML file using the following code:
<canvas id='canvas'></canvas> <script src='/script.js'>
Now, open the script.js file and add the following code to instantiate a new PlayCanvas application:
const canvas = document.getElementById('canvas');
const app = new pc.Application(canvas);
window.addEventListener('resize', () => app.resizeCanvas());
const box = new pc.Entity('cube');
box.addComponent('model', {
type: 'box'
});
app.root.addChild(box);
To create the camera and light for the object, add the following code:
const camera = new pc.Entity('camera');
camera.addComponent('camera', {
clearColor: new pc.Color(.1, .1, .1)
});
app.root.addChild(camera);
camera.setPosition(0, 0, 3);
const light = new pc.Entity('light');
light.addComponent('light');
app.root.addChild(light);
light.setEulerAngles(46, 0, 0);
app.on('update', dt => box.rotate(10 * dt, 20 * dt, 30 * dt));
app.start();
The code above should produce the following result:
Refer to the repo and official documentation to learn more about PlayCanvas.

Nice!
Check out the lib I made. It combines Phaser and Three.js and adds 3D physics to it.
(I plan to support PixiJS as well in the future.)
It is called enable3d.io 🙂
Oh wow, such a great one, I have checked it out, I will see how I could build with it.
I’ve used Isogenic Game Engine (IGE) a few times.
It’s a 2.5d engine with scenegraph-based rendering pipeline and a ton of other features.
Free and open source irrelon/ige on github
Just checked it out, Nice
First you say
“Since Three.js is based on JavaScript, it’s relatively easy to add any interactivity between 3D objects and user interfaces, such as keyboard and mouse. This makes the library perfectly suitable for making 3D games on the web.”
Then you say
“Cons – Not a game engine: If you’re looking for features beyond rendering – you won’t find many here”
Which is it then lol
I made the friGame engine, back in 2011, you can check it out here:
http://frigame.org/
It’s very mature and stable, as it has nearly 10 years of development behind it.
It focuses on compatibility (it’s the only engine that I know of that still supports IE6, other than gameQuery), without sacrificing speed or features.
It’s geared towards 2D games, and all the Cownado ( http://cownado.com ) games are built using friGame.
You can make a text game with plain html, a visual novel or click adventure with just html and graphics, etc. Three.js could make a simple game like this, but with no support for collision detection, it can’t even make pong.
It can, collision detection logic can be created by you, just need some mathematical formulas calculating distance between objects.
I created a ping-pong game with Pygame(2d game engine) which is base on Python.Most of the hardwork was done by me because Pygame lacks alot of features.
Collision Detection can varies with objects like circle, squares or point(Xaxis and Yaxis)
But the Formula you used depends on the game world(2d or 3d).
distance = √(x2-x1)² + (y2 – y1)²
X2 – object A “x” position
X1 – object B “x” position
Y2 – object A “y” position
Y1 – object B “x” position
This will work in a 2d game but haven’t tried it on a 3d game.I used Threejs but It is better of for animations.
3d games are based on X, Y and Z axis.
so the formula should become
distance =
√(x2 – x1)² + (y2 – y1)² + (z2 – z1)²
This Formula for the 3d detection hasn’t be tried by me but I saw it in a text book that has to do with Vectors.This Formula will work when you calculating distances between Points. Other Programmers I know tend to draw a shape around each object and apply a detection formula to it.
