Phaser

Phaser is a fast, free, and fun open source HTML5 game framework that offers WebGL and Canvas rendering across desktop and mobile web browsers and has been actively developed for over 13 years. Games can be built for the web, or as YouTube Playables, Discord Activities, Reddit games, Twitch Overlays or compiled to iOS, Android, Steam and native apps using 3rd party tools. You can use JavaScript or TypeScript for development. Phaser supports over 40 different front-end frameworks including React and Vue. Phaser is commercially developed and maintained by Phaser Studio Inc along with our fantastic open source community. As a result of rapid support, and a developer friendly API, Phaser is currently one of the most starred game frameworks on GitHub. Interested in learning more?

The easiest way to get started quickly with Phaser is our create-phaser-game app. This CLI tool presents an interactive selection of official project templates and demo games. Issue the command, answer some questions and the app will download and configure the right package for you. We support Vue.js, React, Angular, Next.js, SolidJS, Svelte and Remix with Vite, Rollup, Parcel, Webpack, ESBuild, Import Map and Bun. Most come in both JavaScript and TypeScript versions. Don't be alarmed if you look at phaser.js and see a file over 8 MB. Over 84% of that is inline documentation - JSDoc comments, type annotations, and detailed method descriptions that power the TypeScript definitions and API docs. It's there for your IDE, not for your players. The minified build, phaser.min.js , strips all of that out and comes in at 345 KB with standard gzip web server compression. This is the full version, with every feature included, but is still smaller than most texture images. You can reduce it further still by tweaking the build settings to exclude features your game doesn't need. Why Phaser? Battle-tested - Over a decade of active development. Tens of thousands of games shipped. A huge community of developers who've seen it all. Truly cross-platform - One codebase runs on desktop browsers, mobile browsers, and can be wrapped for native app stores, Steam, YouTube Playables, Discord Activities, and more. Developer-friendly API - Scene-based architecture, a comprehensive loader, built-in physics (Arcade and Matter.js), animation system, input handling, cameras, tilemaps, particles, tweens, and much more - all with clear, consistent APIs. Framework agnostic - Works with React, Vue, Angular, Svelte, or plain JavaScript and TypeScript. Use whatever tools you prefer. Massive ecosystem - Over 2,000 code examples. Extensive API documentation. Active Discord and forums. First-class TypeScript definitions. AI-ready - Phaser's API is well understood by every major frontier LLM. This repository includes a comprehensive set of AI agent skills that give coding agents deep knowledge of every Phaser subsystem, making it the ideal framework for AI-assisted game development. Phaser 4 is a major release built on a brand-new WebGL renderer. The entire rendering pipeline from v3 has been replaced with a modern, node-based architecture that manages WebGL state properly, handles context loss gracefully, and is significantly faster. If you've built games with Phaser 3, the public API is mostly familiar - but under the hood, everything has changed for the better. Here are the headline features. For the full picture, see the v4.0 Changelog and Migration Guide. The v3 pipeline system has been replaced with a clean, node-based renderer. Each render node handles a single task, WebGL state is fully managed, and context restoration is built in. The result is a renderer that's faster, more reliable, and much easier to extend with custom rendering logic. Quads now use index buffers, reducing vertex upload costs by a third. Multi-texture batching is smarter, avoiding unnecessary batch breaks on mobile. And the whole system uses just-in-time rend
