Describe a game. Play it in minutes.

Gamemancer is a desktop AI studio that turns a prompt into a real, playable WebGL game — 2D or 3D — with worlds, models, art and sound generated for you. Then export to the web, Unity, or mobile.

What's inside

An agent that forges whole games.

Not a code snippet — a complete, playable game with every asset it needs, built and debugged for you.

Prompt to playable — agentic, self-debugging

The agent plans, writes the code, runs the game in a real browser, watches it, and fixes its own WebGL bugs until it actually works. You describe; it iterates.

2D and 3D engines

Phaser & Pixi for 2D; three.js & Babylon for 3D — plus Gaussian-splat and mesh worlds you can walk around in.

Generate every asset

3D models, rigs & animation, full worlds, images & textures, and audio — all generated from a prompt, placed into your game.

Runs on your machine

Use local models running from your own computer — your prompts, ideas and code never have to leave your desk.

Pro pipelines, optional

Plug in Blender and ComfyUI when you want studio-grade meshes and image generation. Entirely optional — great defaults without them.

Bring your own keys

Connect your own AI providers — API keys or your existing Claude Code / OpenAI Codex subscription. No markup, no per-seat token tax, no lock-in.

Free, cheap, or fully private

Run it on free models from providers like OpenRouter, on low-cost ones like DeepSeek for pennies a session, or entirely on your own machine. You pick the tradeoff between cost, speed and privacy — the app doesn't pick for you.

Export anywhere

Clean WebGL you can host, a Unity project with the scene and gameplay rebuilt, or a mobile app — from one build.

See how any game works — then make it yours.

Point Gamemancer at any game — a classic or the latest viral hit — and it researches how it actually plays: the mechanics, the controls, the feel. Then it builds your own take on it, with your art and your twist. Ride a trend without starting from a blank page.

Beyond single-player

Multiplayer & live services.

Turn a game into something people play together — and keep coming back to.

Real-time multiplayer

Turn any game multiplayer. Players on different devices see each other move, live — in 2D or 3D, any engine. Test it locally in one click, then deploy an always-on server your players connect to. Works on web, mobile, and Unity.

Accounts, saves & leaderboards

Add real player accounts. Sign-in, cloud saves, and leaderboards backed by your own database — each player’s data kept private and secure. It ships in your web and mobile builds automatically, with no extra hosting to wire up.

How it works

From idea to game in four steps.

01

Describe it

Type the game you want — genre, look, mechanics — or ask Gamemancer to research what's working and propose one. Plain language, no engine knowledge needed.

02

Watch it build

The agent generates assets, writes the game, and runs it live — you see it come together in real time.

03

Play & refine

Play instantly. Ask for changes in chat — tweak difficulty, swap art, add a level. It self-fixes as it goes.

04

Export & ship

Send it to the web, a Unity project, or a mobile app — clean output you fully own.

Made for makers

One tool, every kind of maker.

The magic of no-code, the depth and privacy professionals need.

For creators

No code. Just play.

  • Describe a game and get something playable in minutes — no engine, no boilerplate, nothing to install beyond the app.
  • Generated art, models, worlds and sound, so a blank canvas is never the starting point.
  • One-click to a mobile app — your game on your phone, ready for the stores.
  • Pay only for what you generate with your own cheap API key — no rigid monthly tier.

For studios

Prototype at the speed of thought.

  • Test a mechanic in minutes instead of weeks — kill bad ideas before they cost a sprint.
  • Bring your own keys and run local models — proprietary concepts never leave your machine.
  • Export a Unity project with the scene and gameplay rebuilt natively — bridge web prototype to production.
  • Plug in Blender & ComfyUI and your own asset libraries for studio-grade pipelines.

For marketers

Ads people play, not skip.

  • Ship a playable ad concept in minutes — prove the hook before you commit the media spend.
  • Clean, lightweight HTML5 that drops straight into your ad network or a landing page.
  • Generate on-brand characters, art and worlds — no stock hunt, no asset backlog.
  • A/B a dozen creative variants in chat, for the cost of one designer's afternoon.

For educators

Turn any lesson into a game.

  • Turn a topic or lesson into a playable game — describe it, no coding required.
  • Custom art and worlds built around your subject, so every game fits the material.
  • Share a web link or send it to phones — the same game, everywhere your class is.
  • Adjust difficulty and content in chat as fast as the curriculum changes.

For agencies / freelancers

Client games, without a dev team.

  • Pitch with a working prototype, not a slide deck — win the client before you scope the build.
  • Deliver interactive work for a fraction of a studio budget — no engineers on the payroll.
  • White-label clean web, Unity or mobile output your client fully owns.
  • Turn one brief into three concepts in an afternoon — iterate live in chat.

For brands & community teams

Turn a campaign into a game.

  • Launch a branded mini-game for a drop, event or campaign — live in a shareable link.
  • On-brand characters, worlds and art generated to match your identity — no asset scramble.
  • One-click to the web or a phone — meet your audience wherever the campaign runs.
  • Spin up seasonal variants in chat — a new game for every moment, not every budget.

Export

Build once. Ship everywhere.

Your game isn't trapped in our app. Take it to the platform you need — no rewrite.

Web

Clean, lightweight HTML5/WebGL you can drop into any site or host as-is. No engine, no bloat — pure vanilla output you own.

Unity

A Unity project with the world, camera, lighting and props rebuilt deterministically — and the gameplay ported to native C# on top.

Mobile

A ready-to-build React Native / Expo app wrapping your game — straight to a phone, ready for the app stores.
