Framework

Phaser

Phaser is the default framework for 2D games that run in a browser — JavaScript, MIT-licensed, and it ships with the boring parts already built.

Phaser is a 2D game framework for the web, written in JavaScript with first-class TypeScript support, released under the MIT licence. The single thing that defines it: your game is a web page. There is no separate export step to worry about, no runtime to install for the player — it runs where a browser runs, which is nearly everywhere.

If your game is 2D and the target is a browser, the interesting question is not "why Phaser" but "why not Phaser". It comes with physics, input, tilemaps and audio already wired up, and it sits on top of the largest tutorial pile in web game development. You are rarely the first person to have your problem.

What it is good at

Getting a sprite moving on screen fast. The API is arranged around the things you actually do — load an image, add it to a scene, give it velocity, check if it hit something — and the loop that ties them together is short. You can have a controllable character bouncing off walls before you've finished your coffee.

Batteries genuinely included. Arcade physics for fast, simple collision, plus a heavier physics option when you need real bodies and joints. Tilemap support that reads the formats level editors already export. Audio, keyboard, mouse, touch and gamepad handling out of the box. You are assembling parts, not machining them.

Being the web. There is no build-and-upload dance to see your game on a device — you point a phone at a local address and it's there. Distribution is a link. Itch.io, a portal, an ad on a friend's blog, an embed in a page you already own. For a jam or a prototype that needs to be in someone's hands in the next hour, that immediacy is hard to beat.

TypeScript that actually helps. The type definitions are thorough enough that autocomplete becomes a form of documentation, which matters in a framework with this much surface area. You can discover half the API by pressing dot and reading.

The tutorial mass. Whatever you're stuck on — a jump that feels right, a camera that follows without nausea, a save system in local storage — someone has written it up, probably several times. The answers occasionally disagree, which is its own kind of adventure, but the raw volume means you are rarely stranded.

What it is not good at

3D. Phaser is a 2D framework and does not pretend otherwise. If your game has a camera that moves through space, this is the wrong tool and no amount of clever layering will fix that.

Native platforms. The export target is the browser. Getting a Phaser game onto a console, or into a proper native desktop or mobile app, means wrapping it in something else — a web-view container, a packaging layer — and inheriting whatever compromises that wrapper brings. It is done all the time, but it is a second project bolted onto the first, not a checkbox.

Editor-driven workflows. There is no scene editor, no visual node graph, no drag-a-thing-onto-the-canvas. You write code. If you came from an engine where you place objects with a mouse and wire up behaviour in a panel, expect to miss that. Everything in Phaser lives in your source, which some people love and some people find exhausting.

Asset weight and load times. Because it runs in a browser, your player downloads the game before they play it. That is fine for something small and disciplined; it becomes a real constraint when your art and audio balloon. Managing what loads when is your job, and it's a job you don't have in a world where the player already installed a 40GB build.

The wilder edges of performance. It is capable, and plenty of games run smoothly, but you are ultimately at the mercy of a browser tab, JavaScript's garbage collector, and whatever the player's device decides to throttle. Squeezing the last frame out of a bullet-hell with thousands of entities takes care and profiling that a native runtime would spare you.

Who should pick it

Web developers, first and foremost. If you already think in JavaScript or TypeScript, know your way around npm, and are comfortable in a browser's dev tools, Phaser meets you where you live. Your existing skills transfer almost completely, which is not something you can say about jumping into a big general-purpose engine.

People shipping 2D games where the browser is the point. Web portals, embeddable games, marketing minigames, io-style multiplayer arenas, jam entries that need to be playable from a link. Anything where "click and play, no install" is a feature rather than a limitation.

Solo developers and small teams who value a short path from idea to running thing. The lack of an editor is a cost, but it's also fewer moving parts and a codebase you fully understand.

It is a poor fit if you're chasing console launches, building in 3D, or planning a large premium title where a native store page is the business model. Those are real games, just not the games Phaser was shaped for.

Getting started

The fastest first hour is a starter template. Grab one that pairs Phaser with a modern bundler so you get live reload and TypeScript without hand-configuring anything, and get a blank scene rendering. Seeing the canvas appear is the whole battle for five minutes.

Learn the Scene next — it is the unit everything else hangs off. The three lifecycle methods (preload, create, update) are the spine of every Phaser game: load your assets, set up your objects, then run the per-frame logic. Understand that rhythm and most tutorials suddenly make sense.

Then add arcade physics and make something collide. A player sprite, a ground, gravity, a jump. That single exercise touches loading, input, physics and the update loop at once, and it's the moment Phaser stops feeling like a library and starts feeling like a game.

Keep the official examples open in another tab. They are runnable, editable, and the fastest way to find the one method call you're missing. Check phaser.io for the current documentation and whatever licensing details you need — the framework is MIT, but the surrounding tools and templates each carry their own terms.

Best for

Web developers who already know JavaScript or TypeScript and want a 2D game running on a URL, not a download page. Game jammers who need something playable by tomorrow.

Not the right pick for

Anyone building 3D, targeting consoles, or shipping a heavy native desktop title. Phaser exports to the browser and only the browser, and that is the whole point.

Frequently asked questions

Do I need to know JavaScript before starting?
Effectively yes. Phaser is a code-first framework with no visual editor, so you'll be writing JavaScript or TypeScript from the first line. If you're brand new to programming, learning the language basics first will make the framework far less frustrating than trying to learn both at once.
Can I release a Phaser game on Steam or consoles?
Not directly. Phaser's official export target is the browser, so reaching desktop stores or consoles means wrapping the game in a separate container or packaging layer. It's commonly done, but treat it as additional work and additional constraints rather than a built-in feature.
JavaScript or TypeScript — which should I use?
Either works, and TypeScript is well supported with thorough type definitions. If your project is anything beyond a quick prototype, TypeScript's autocomplete and error-catching pay off quickly, partly because they help you navigate the framework's large API. For a tiny jam entry, plain JavaScript is perfectly fine.
Is Phaser free to use commercially?
The framework is released under the MIT licence, which is permissive and commercial-friendly. Any surrounding tools, plugins or templates you add will have their own licences, so check those separately. For anything about paid services or tooling, consult the official site rather than assuming.
Will a Phaser game perform well on phones?
It can, but you're running inside a mobile browser, so you're subject to that device's throttling, memory limits and garbage collection. Small, disciplined games run smoothly; heavy ones with thousands of on-screen entities need profiling and care. Managing asset size and load times is your responsibility since the player downloads the game before playing.
