Phaser AE

Make games with the coding agent you already use.

Phaser AE works in 76 coding agents.

The quick way

Let your agent set it up.

Paste this into your agent. It checks for Node.js, runs the setup and opens your browser so you can sign in, then takes you to design your first game. You only do this once.

Paste this into your agent

Set up Phaser AE for me, so I can make games with you. Check that Node.js 20 or later is installed, and install it if it isn't. Then run npx -y @phaser-ae/cli setup: it opens my browser so I can sign in to phaser.io and approve Phaser AE, and it installs the Phaser AE skill. When it's done, tell me, and open https://phaser.io/agent/new in my browser so I can design my first game.

Step one

Pick your agent.

Before you start

What you need.

Node.js 20 or later

The CLI runs on it. Type node --version in a terminal to see yours; nodejs.org has the installer.

A phaser.io account

Free, and it's what the CLI downloads the Phaser AE engine and its expansion packs under, and publishes your games to. The first time, your browser opens so you can sign in. No account yet? Make one in a click with Google, GitHub or Microsoft.

A coding agent

Claude, Codex, Cursor or any of the agents above. You talk to it, and it runs every command for you, on the plan you already have.

Or see what happens

Set it up, step by step.

  1. Check Node.js

    Version 20 or later. If the command isn't found, or says something older, install it from nodejs.org.

    node --version

  2. Run the setup

    In any terminal (your editor's will do). npx fetches the @phaser-ae/cli package from npm and runs it: your browser opens so you can sign in to phaser.io and approve Phaser AE, then it puts the Phaser AE skill in the folder each one reads its skills from, for every coding agent on your computer.

    npx -y @phaser-ae/cli setup

Your first game

Design it first. Build it with your agent.

Your first game design free

An empty prompt box is a hard place to start a game. On phaser.io you design yours, a step at a time, into a complete game design document: how it plays, how it looks, every level and every rule. Your agent builds the game from that, and the result is a world apart from a one-line idea.

Design your first game

  1. Start a new game on phaser.io

    Signed in with the same account. Say what you'd like to make, then answer a few questions: what it's played on, how it looks, who it's for.

  2. Shape your game design document

    Everything the game needs, written up in one document you can read and change. Your first one is free.

  3. Add the art and sound, if you like

    With credits, phaser.io makes the sprites, music and sound effects to go with it. You don't have to: without them, the game is drawn in code.

  4. Hand it to your agent

    When the document is ready, phaser.io shows you how. Your agent builds the game from it, plays it to check it, and publishes it, ready for you to playtest.

Rather start from an idea? Ask your agent for “a Phaser AE game” and it starts one straight away. How it works

Once it's built

You talk. Your agent does the rest.

  • Play it and fix anything that feels wrongIt plays the game in a real browser, finds what’s off and fixes it
  • Bring down my playtest notes and make themWhat you marked up on the playtest page, made in the game
  • Find a pack for fog of war and add itIt searches the expansion packs and adds the one that fits
  • Publish itThe next version, on phaser.io

What it costs

Your agent's plan does the building.

  • Your first game design free. Design your first game on phaser.io for free, and build it with your agent for free.
  • Each design after that uses credits, from 200 a design.
  • Building is on your agent's plan. No phaser.io credits for the build, the playtests or publishing.
  • Art, music and sound use credits. If you'd like them, phaser.io makes the assets to go with your design.
  • 163 expansion packs are free. Pro adds the other 174, and as many game designs as you like. Pricing
