Describe a game, and the agent designs it, makes the art, writes the code, plays it to check it works, and publishes it to a link anyone can open. Design docs, images, video, 3D, and audio live on one canvas next to the code, instead of across five different apps.

[!NOTE] OhMyGame is in beta. Expect rough edges, and tell us what breaks.

Download

Older builds and release notes are on Releases. The Windows build isn't code-signed yet, so SmartScreen may warn on first install. Intel Mac and Linux are on the roadmap.

OhMyGame ships without a model. On first launch, connect a provider or a coding agent you already use: first run.

Features

• Let the agent build the game. The agent drafts the design doc, writes the code, runs the game in a live preview, then plays it and tries a fix when something breaks.
• One canvas for every asset. Generate images, video, 3D models, animation, voices, sound effects, and music with AI, and keep them organized on one canvas, ready to use in your game.
• Publish to a link. Anyone can play it in the browser, and it shows up in the Community. A multiplayer game's rooms, and its players' sign-in, saves, and leaderboards, come with it.
• Extend it with plugins. A plugin can teach the agent new skills, give it new tools, and add panels and project types to the app. Bundled plugins cover Godot, Unity, Unreal Engine, Blender, Aseprite, Tiled, and platforms like WeChat and Douyin Mini Games. Or make your own.
• Bring your own agent. Run OhMyGame on Claude Code, Codex, or OpenCode, or on any of 40+ model providers with your own keys. No per-run credits. It works the other way too: use the canvas, media generation, and playtesting from your agent over MCP. Models · External agents

What you can make

Three games our team made with OhMyGame:

Interactive film	Island builder	Deckbuilding roguelike

Web games (Phaser, Three.js, React Three Fiber) are the best place to start. Interactive stories cover visual novels, interactive films, and story games. General games work with any engine or stack. Web games can be multiplayer, from board and card games to realtime arenas, played online with friends with no server of your own. See Multiplayer. Play what others made.

Documentation

Guides for using OhMyGame are at ohmygame.ai/docs: install, first run, models, and plugins.

Technical references live in this repo under docs/, such as the runtime, coding agents, custom models, and the plugin contract.

Build from source

Requires Bun 1.4.2+ and Node.js 22.19+.

git clone https://github.com/WhiteTowerAI/ohmygame.git
cd ohmygame
bun install --frozen-lockfile

Privacy

Your projects and API keys stay on your machine, and prompts go straight to the providers you choose. You only need an account to publish. Release builds send usage data and crash reports, which you can turn off in Settings → About. See logs and diagnostics.

Contributing

Issues and pull requests are welcome. Branch from dev and open PRs against dev; main holds releases. Read CONTRIBUTING.md, pick up a help wanted issue, and report security problems privately through SECURITY.md.
