Phaser

What is Phaser?

Phaser is a JavaScript game framework created by Richard Davey and first released in April 2013. It grew out of earlier experiments with web game engines and quickly became the most popular HTML5 game framework, powering everything from tiny browser puzzlers to full commercial web games.

Instead of a desktop editor, Phaser is a code-first toolkit: you write JavaScript or TypeScript, and Phaser handles rendering, physics, input, audio, tweens and scene management for you. Games run on WebGL with a Canvas fallback, so they work on phones, tablets and desktops without any installation.

Because it is just a JavaScript library, Phaser plays nicely with the modern web stack. You can bundle it with Vite or webpack, write game logic in TypeScript, and deploy the result to any static host, which makes it a natural choice for developers already comfortable with the web.

Key Features

• WebGL rendering with automatic Canvas fallback
• Scene system for cleanly splitting game states and screens
• Built-in Arcade and Matter physics engines
• Sprite, animation, tween and particle systems
• Input handling for mouse, touch and gamepads
• Audio support with Web Audio API
• Loader for assets like images, atlases, audio and tilemaps
• Active plugin ecosystem and a friendly global community

How to get started

You need a web development setup: Node.js, a text editor and a browser. The Phaser website offers a getting started guide, and the official examples page is the best place to browse working snippets, from moving sprites to complete mini games.

For a modern workflow, scaffold a small project with Vite and install Phaser as an npm package. Then create a game config with a scene, add sprites and use the update loop to animate them. There are also community templates and the Phaser Editor IDE for developers who prefer a visual scene editor.

• Install Node.js and create a project folder
• Install Phaser with npm install phaser
• Copy a basic template from the Phaser getting started guide
• Explore the official examples to learn scenes and physics
• Build your game and deploy the static files to any web host

Use cases

• Browser games playable directly from a website link
• Mobile-friendly 2D games distributed on the web
• Educational games and interactive marketing experiences
• Game jams and prototypes where shipping fast matters
• Mini games embedded in apps and platforms like Poki
• Learning JavaScript through game programming

Pricing and licensing

Phaser is free and open source under the MIT license. You can use it in commercial games, closed-source projects and client work with no royalties and no attribution requirements, and you can modify the framework itself.

The project is funded through Phaser Studio and community sponsors. There is a paid tier in the form of Phaser Editor, a visual editor for Phaser projects, but the core framework and all of its documentation and examples are completely free.

Pros and cons

Phaser's strengths are its web-native nature, its speed and its accessibility. Games deploy as static files that run anywhere with a browser, the API is well documented with thousands of examples, and if you already know JavaScript there is almost nothing new to learn.

The trade-offs: it is code-only, so there is no visual editor in the core package, and the framework targets 2D web games specifically. For 3D you would look at Three.js or Babylon.js, and for desktop-native releases you would pair Phaser with Electron or choose a different engine entirely.

Alternatives

• Three.js: JavaScript 3D graphics library for the browser
• Babylon.js: full web 3D engine with an editor toolchain
• Construct 3: no-code 2D game maker that exports to the web
• PixiJS: lightweight 2D WebGL renderer for web games and apps
• Unity: exports browser games via WebGL
