Games made with Codex

Codex runs as an open-source command-line tool under the Apache-2.0 license, as an IDE extension for VS Code and Cursor, in the ChatGPT desktop app and as a cloud agent at chatgpt.com/codex.
For a game, you point it at a project folder and describe what to build or fix. The desktop app's built-in browser previews a local dev server and takes screenshots, and Codex can generate images too, including sprite sheets, backgrounds and UI assets, so the art can come from the same place as the code. MCP servers connect it to engines, and Unity's official server and the community Godot AI server both list Codex as a client.
As of September 2026, every ChatGPT plan includes Codex, from Free and Go to Enterprise, so you don't really need a paid plan, and the CLI and IDE extension also run on an OpenAI API key.

Only 15 of the 101 name an exact model version, most often Claude Opus 5.5 (7). We record a version only when the creator states it.
18 games also name another AI family (Claude on 16, Gemini on 5 and DeepSeek on 1).
23 games name a second tool as well, most often Claude Code (13).
