Free AI game maker built on Godot: Make beautiful games with AI.
Describe the game you have in mind. Flockbay’s AI builds it in the full Godot editor, from the world and the characters to the physics and the GDScript behind them, and plays it to check its own work. Or bring your own Claude Code, Codex or Cursor over Godot MCP. You play it and shape it until it is the game you imagined.
AppImage, x86_64. Ubuntu 22.04, Debian 12, Fedora 39 or newer.
Intel or AMD Chromebook, with Linux turned on.
Made in Flockbay
Real games, built with AI
A truck that climbs a mountain on working suspension. A six-legged walker crossing a canyon. A house where a guard walks his rounds through the doors. Each was built by AI in Flockbay, on the official Godot engine, and played by a person. These are captures of the running games.

Grey-box to final look
It starts as a grey-box. It ends up beautiful.
Flockbay builds the mechanic first, in grey-box, so you can play it while it is cheap to change. Once it feels right, the AI dresses it: models, materials, lighting and the HUD. Same game, two passes.
Our commitment
Beautiful games, never slop
We build Flockbay for games worth playing: made with AI, played by people, and polished until they are beautiful. We put that in writing, along with how we will be open about AI in games.
How it works
Describe it. Play it. Make it yours.
You open a Godot project in Flockbay, pick Claude or ChatGPT, and ask for a door that opens when the player walks up to it. Your AI writes the GDScript, runs the game, reads the errors and captures the viewport to check its work. You press F5, walk up to the door, and say what was wrong. That is the loop.
- Describe itA mechanic, a level, a look. A jump that feels right, an enemy that turns around at a ledge, a sky at dusk.
- Play itPress F5. Your AI has already run it too: headless runs, stdout, parse errors and viewport captures.
- Shape itSay what is off and play it again. Keep going until it is the game you imagined.
What it is
Flockbay is a free AI game maker built on Godot. It is a desktop app that hosts the full Godot editor and adds a chat, world tools and playtesting tools your AI calls. The engine is the official Godot 4.7.2, not a fork, and the game is a real Godot project you can open and change.
Who it is for
It is for developers who already pay for Claude or ChatGPT. Flockbay runs Claude Code, Anthropic's coding agent, on your Claude Pro or Max plan, or your ChatGPT sign-in on any plan, Free included, behind its own chat. An agent you run yourself, such as Cursor or Codex, connects over MCP. If you want an engine with no AI in the loop, Unity is the honest other choice.
The editor
The full Godot editor, with Flockbay added
The Scene dock, the Inspector, FileSystem, the Script editor and the Asset Store are Godot’s own. The chat is a dock beside them, and Flockbay’s tools sit around the 3D and 2D view. On Windows and Linux.
World tools
Terrain, water, sky, weather, the player controller and props are systems your AI calls by name. The same controls sit around the 3D and 2D view for you: Sculpt, Paint, Plants, Place, Water, Sky, Weather, Characters, People and Camera.
Playtesting
Your AI runs the game headless or in the Game screen, reads stdout and GDScript parse errors, captures the viewport, injects input events, and reads and changes the live scene tree.
A modeler
Your AI builds rigged, game-ready 3D models from a spec, on your computer, with no key and no cost. A model lands in assets/Models as a glTF binary with its materials.
Your existing Godot project
Open a project made elsewhere. Flockbay asks once before adding anything and lists what it adds, and Remove Flockbay from this project takes it all out.
2D or 3D
Nothing is created until you pick 2D or 3D
A new project asks which kind of game, as two pictures, and there is no default. Nothing is created until you choose.
Pick 3D and you get a world you can walk: terrain you sculpt, water, sky, weather, a player controller and the props you place.
Pick 2D and it opens already playable, with tile terrain, a ledge, a platform, and a player controller that walks, falls and jumps. You drag to lay tiles and drag to erase them. The tiles, the edges and the collision shapes come from which cells are filled.
Side-on and top-down are not a menu choice. Turn gravity on and down is a direction, so a jump exists. Turn it off and the character steers on both axes. For art, you search the Catalogue by name and download a sprite into the project, generate a single flat image on your own key, or import a file of your own.
Ask for one behaviour at a time. An enemy that turns around at a ledge, or a score that goes up when you pick something up. You press F5 and say whether that one thing is right.
Your files
The game ends up on your computer
It is a Godot project in a folder
The engine is Godot, which is open source, and a copy of it comes with the app. The app itself is not open source. Your project is an ordinary Godot project in a folder on your computer: scenes, GDScript and a project.godot. Stock Godot can open it, and a Godot project you already have opens in Flockbay. The game runs locally on the bundled copy. Playing does not need a connection.
Building does. The chat, generated art, and the data for the world all come over the network. With no internet, you cannot build. Flockbay is a Windows release first: a 64-bit PC with an Intel or AMD processor. The Mac build, for Apple Silicon, is an earlier release: it does not yet run Claude in the app or host the full editor. On Linux it is an x86_64 AppImage for Ubuntu 22.04, Debian 12, Fedora 39 or newer. On a Chromebook with an Intel or AMD processor, the same AppImage runs in ChromeOS’s Linux environment. There is no browser version and no phone version.

Your Steam store page, ready to upload
Flockbay prepares your game’s Steam store page, with the capsules, the screenshots and every text field, and exports it as a .zip you upload in Steamworks yourself.

What an AI game maker is covers the category and where a desktop app on a real engine sits in it. How that sits on Godot is the same fact from the engine's side. If you have been looking at Summer Engine, Flockbay versus Summer Engine says where each one fits.
Price
Free, AI included
- Free AI every day
- Your Claude or ChatGPT
- Your agent over MCP
- Your own API key
Flockbay is free, and so is its AI. Every account gets free AI each day on Flockbay's hosted model, with nothing to connect. Or build on your own AI: your Claude or ChatGPT plan in the app, your own agent over MCP, or your own API key, and you pay the company that runs your model, never Flockbay. Sculpting terrain, laying tiles and placing props need no AI at all. Generated pictures and sound come with the free AI; 3D models run on your own Tripo key, and without one, Flockbay builds from a library of ready-made objects, or with Godot's own shapes.
Plans for more hosted AI are optional. Projects and assets are private, and there is no team plan and no per-seat price. What free covers is on its own page. You build in the Godot editor, and you can open and change the project.
FAQ
Questions
- What is Flockbay?
- Flockbay is a free AI game maker built on Godot: a desktop app for Windows and Linux whose AI builds and play-tests a real Godot 4 project inside the full Godot editor, on free AI every day or your own Claude or ChatGPT. The project is an ordinary Godot project on your own disk, on the official engine, not a fork, and the game runs locally. Building needs an internet connection. There is no browser version. The name is Flockbay.
- What the AI does
- Flockbay's AI, on its free hosted model or your Claude or ChatGPT in the chat, or your own agent over MCP, writes GDScript and scenes into your Godot project. It calls Flockbay's world tools for terrain, water, sky, weather, the player controller and props, builds rigged 3D models with the modeler, and playtests the game: a headless run, stdout and parse errors, viewport capture, input events and the live scene tree. You judge the result by playing it.
- Platform
- Windows and Linux: the current release runs on 64-bit Windows with an Intel or AMD processor and as an x86_64 Linux AppImage, and the Mac build is an earlier release, without Claude in the app or the full editor. There is no web version, no browser editor, no browser preview, and no mobile app.
- Who writes the code
- Your AI does, and you can: it writes the GDScript into a real Godot 4 project, and Flockbay hosts the full Godot editor, Script editor included, beside the chat. You can open, read and change every file there, in stock Godot or in your own code editor.
- Where the game runs
- Output is a normal Godot project in a normal folder on local disk. Games run locally on the copy of Godot bundled with the app. No streaming, no cloud rendering, no cloud building.
- Pricing
- Free, AI included. Every account gets free AI each day on Flockbay's hosted model. Or build on your own AI: your Claude plan (Pro or Max) or your ChatGPT account (any plan, Free included) in the app, your own agent over MCP, or your own API key (OpenAI or Anthropic), and you pay the company that runs your model, never Flockbay. Optional plans add more hosted AI: Hobby at $20, Indie Developer at $60 and Studio at $200 a month. There is no team, per-seat, or enterprise plan. Projects and assets are private.
- AI models
- Free AI runs on Flockbay's hosted model, Demo in the model menu, which Flockbay picks. On your Claude plan, Flockbay runs Claude Code, and the model menu lists the models and effort levels Claude Code gives you. On your ChatGPT plan, it runs your account's models through the bundled Codex engine. On an API key, it runs any model the key reaches, and an agent over MCP uses whatever model that agent runs.
