OhMyGame

OhMyGame puts everything you need to make games with AI in one app: describe your game, and the agent designs it, makes the assets, builds it, plays it to check it works, and publishes it to a link you can share. It is open source and works with 40+ model providers through Pi, from Anthropic and OpenAI to DeepSeek and Qwen. Your keys stay on your machine, there are no per-run credits, and what you make is yours.

Agent: drives the canvas, builds and plays the game. The agent drafts the design doc, lays out boards, and generates assets on them. Then it reads the design doc, writes the code, and runs the game in a live preview. It opens the game in a window you can watch and plays it, including real-time canvas and WebGL games. When it finds a problem, it tries a fix and plays again. Along the way it can generate images, video, and 3D models, search the web, and use MCP servers or the Codex and Claude Code plugins you already have.

Canvas: design docs, art, video, and 3D on one board. Every game project has a design space: a main design doc plus boards where the doc, images, video, and 3D models sit side by side. Nodes can use each other as references, so one character design can lead to more images, a video, or a rigged and animated 3D model. Results go into a shared Asset Library that your games can use.

Publish: one link, playable anywhere. Sign in and publish: OhMyGame builds your game and gives it a link anyone can play in the browser. Republishing updates the same link. Published games are listed in the in-app Community, where you can play what others have made.
