What is Shiny Gen?

Shiny Gen is an AI game maker that runs in your browser: describe a game, play it, and edit its assets, code, and world with built-in AI tools. Games run on the Godot engine and are written in GDScript. Shiny Gen is free to use, with paid credits for AI generation only. It also ships an MCP server so AI assistants like Claude and ChatGPT can build alongside you, and a shinygen npm package for embedding games on the web. The Android app is on Google Play; the iOS app is coming soon.

Think of it as a sandbox with an AI asset editor built in: describe what you want, and it appears in a world you can play and share.

How it works

1. Describe a game. Type what you want in plain language: a genre, a scene, a mechanic, or a whole idea.
2. The AI writes real game code. Shiny Gen generates GDScript (the Godot engine's scripting language) and runs it immediately on the engine in your browser.
3. Play it instantly. The game runs as it is built. There is nothing to install and no engine to learn.
4. Edit anything with the built-in editors. Shiny Gen has four AI creation surfaces: a game-code editor (GDScript), a 3D model editor, an image editor, and audio generation for sound effects and music.
5. Share it. Every game can be shared with a link. Games you own can also be exported for the web as a zip you can host anywhere, or embedded on any website with the shinygen npm package.

What makes Shiny Gen different

It is browser-native and a real game engine

Most AI game tools are one or the other. Prompt-to-game websites are instant but keep your game inside their own runtime. Engine-based AI tools produce a real project but run as desktop software. Shiny Gen is both at once: it runs entirely in the browser, and what it builds is a real Godot project written in GDScript that you own.

It is a whole game engine, not just a renderer

Web games built with Three.js get a 3D renderer, and everything else is hand-written: physics, input, scenes, cameras, tooling. Shiny Gen puts the Godot engine itself in the browser (physics, scenes, input, audio, and editors included) running on a WebGPU renderer compiled to WebAssembly. The AI writes GDScript against a full engine, so a described game becomes a playable game without anyone building engine plumbing.

Its MCP server is hosted, not a desktop bridge

Shiny Gen ships a remote MCP (Model Context Protocol) server at mcp.shinygen.ai. Press Host External Agent in the app, connect Claude, ChatGPT, or any MCP client, and the assistant can read your project, write code, generate assets, and run the game, live, in your browser project. Other game-engine MCP integrations are bridges to a desktop editor running on your machine; Shiny Gen's is hosted, with nothing to install, and access is controlled by scoped OAuth permissions.

Games live on the web

A Shiny Gen game is a link anyone can open. Its owner can also export it for the web as a zip to upload to itch.io or any web host, with its engine version pinned so it keeps working the same way, or embed it on any website via the shinygen npm package.

What Shiny Gen is not

• Not a hosted prototype box: your game is a real Godot project you own, not a clip locked to one page.
• Not just a 3D renderer like Three.js: it is a whole game engine, so you do not hand-code physics, scenes, or tooling.
• Not a desktop download: it runs in the browser, and as an Android app on Google Play, with an iOS app coming soon.
• Not a Godot plugin: it is a standalone product built on Godot; you never install Godot.
• Not related to Shiny, the R/Python web framework by Posit.
• Not related to Pokémon shiny hunting.
