Phaser is introducing the Phaser Game Agent: describe a game in a single sentence, and the agent designs, builds, tests and ships it for you. No code, no art tools, no waiting around watching a progress bar. You write what you want to play. It handles everything else, including the code, art, and sound.
This isn't a thin wrapper that asks an AI to write Phaser code from scratch and hopes for the best. That approach is exactly what produces generic, half-broken AI slop: hallucinated APIs, inconsistent physics, placeholder art. The Phaser Game Agent works differently, because the engine and the content pipeline underneath it were built from the ground up for an AI audience, not bolted on afterwards.
How the Phaser Game Agent Builds a Game from One Sentence
Building a game with the Phaser Game Agent happens across three screens.
1. Concept
The first screen is Concept. You type what game you want, one sentence is enough, or click Surprise Me for a random idea. If you'd rather not write anything, there's a list of ready-made concepts to pick from, things like Alien Invaders, Tunnel Digger, Pet Care, or 3D Canyon Chase, with a Show More button if none of them grab you. A Game Title field is optional. Leave it blank and the agent invents one for you.
2. Art Style
Second screen is Art Style. Pick from a set of style options, things like Disco Fever, Elven Forest, PS1 Lo-Fi, Solar Punk, or Stained Glass, or skip the presets entirely and describe the look you want in your own words, anything from neon and rain-soaked to hand-drawn and cozy.
3. Agent
The third screen is Agent, where you choose which model builds your game. There are three tiers: Kilo (GLM 5.2), Sonnet (Claude Sonnet 4.6) and Opus (Claude Opus 4.8). Bigger agents craft better games in fewer steps. Smaller agents cost less. Each tier has a minimum credit balance to launch, but that's not what the game will actually cost. Nothing is charged until the agent starts working, and the final cost can be lower or higher depending on what you asked for and how many iterations it takes.
Hit Build Game and the agent takes over. Walk away, and it'll email you the moment your game is ready to play and share with a link anyone can open instantly in the browser.
2D Arcade, Vector, and 3D Games: A New Phaser Engine for AI Agents
Most frameworks make the AI learn them. The Phaser Game Agent flips that: it runs on a brand-new Phaser engine built around how an AI agent actually works. A verb-based, component API that assembles itself on demand, carrying only the pieces a given game needs, whether that's a 2D arcade game, a vector world, or real 3D. Here are just a handful of the features the engine ships:
Sprites, tiles & physics
Swept collision, tilemaps, particles, animation, juice and sound. Everything a classic platformer, shooter, or puzzler needs, generated art and all.
Crisp line-art games
Asteroids, Lunar Lander, Thrust. Glowing polygon worlds with destructible terrain, slope physics, and shatter-into-fragments deaths.
Real 3D worlds
Kart racers, rail shooters and first-person mazes with real meshes, lights, shadows and terrain. Something Phaser has never done before.
Phaser AE: A Framework Built for How Agents Think
Under the hood, the Phaser Game Agent runs on Phaser AE: a framework rebuilt from scratch specifically for an AI audience rather than a human one. This is the part that actually separates the Phaser Game Agent from a generic AI code generator. Most frameworks, including Phaser itself, were designed for humans who build a mental model over weeks. Hand that same sprawling API to an AI and it degrades: too many functions, too little signal, hallucinated lookalikes. Phaser AE's API maps to how an agent actually reasons, in verbs and intentions, with the hard, bug-prone stuff like collision and pooling hidden behind a surface small enough for an agent to hold in its head all at once.
Games are assembled from a library of reusable, capability-named components carrying real, known-correct code, not generated from scratch each time. A human plays every new game before its reusable parts get harvested back into that library, so the system improves with every build. Each conversation runs inside an isolated Superserve sandbox with everything prebuilt, so the agent's effort goes entirely into the game itself: pulling components, generating art and sound, wiring it together, and running acceptance tests before it publishes.

Phaser Framework and Phaser Editor: For Developers Who Want Full Control
The Phaser Game Agent is for anyone who wants a game without touching a line of code. If you're a professional developer or you simply want full control, Phaser's free and open-source framework and the dedicated Phaser Editor are still exactly where you left them. Every line yours, no agent required 🙂
Your next game is one sentence away
No code, no art tools, no waiting around watching a progress bar. Describe what you want to play, choose your agent, and walk away. When it's ready, you'll get an email with a link to your finished game, fully playable in the browser, with its own URL you can send to anyone, no account or download required.
