Make a game with AI for free: what free actually gets you

The app costs nothing to download, on Windows, macOS or Linux, and nothing to use. The engine underneath is Godot, which is open source and free in the stronger sense of the word.

The AI is free. Flockbay builds your world and writes your gameplay logic on hosted AI that is free every day, with no sign-up, or on your own: your Claude or ChatGPT (a free ChatGPT account works), your own agent over MCP, or an API key. Flockbay builds from a library of ready-made objects, or with Godot's own shapes. When the AI is your own, what it costs is between you and the company that runs it. Flockbay itself is free.

The rest is what you would hope for. There is no watermark, no export fee, no revenue share, no locked engine feature waiting behind a payment, and it is free for one person or a team.

Every time a model runs there is a bill. Any tool that offers unlimited free AI is either sitting on someone else's money temporarily or serving you something very cheap and hoping you do not notice. Flockbay pays for a daily allowance of hosted AI, and it comes back the next day. Past it, your own Claude, ChatGPT, agent or API key carries on, and that bill is between you and the company that runs it.

The useful thing to know is that not every change has to be a prompt. The world tools Flockbay builds with are also buttons around the Godot editor's own 3D and 2D view. Nudging a hill, moving a lake, changing the weather or repainting a path by hand is you working, not tokens burning, and so is repainting a few cells of a flat game's tile ground or dragging one sprite to an exact spot. Godot's undo takes any of it back.

So the daily allowance, or your own AI, goes further here than in a tool where every action is a prompt. Ask for the big moves in sentences, make the small taste calls by hand, and Flockbay itself costs nothing either way.

A desktop app for Windows, macOS and Linux with Godot bundled inside. A project that is a genuine Godot project on your own disk. A game that runs locally on your hardware at your machine's framerate, with no streaming and no browser tab.

And the working loop: Flockbay agrees a brief with you, builds the world, writes the GDScript and plays its own work to check it runs; you play the result and say whether it is right. The by-hand tools in the editor need no AI at all.

Building needs an internet connection. The chat, asset generation and world data all come over the network, so this is not a tool you can use on a train. Playing the game you built does not need a connection.

It is also a download rather than a website. If your reason for searching "free" was really "I do not want to install anything", that is the honest answer: this installs. What you get for it is local performance and a project you own.

Ask for behaviour in whole pieces rather than one adjustment at a time. "The player takes damage from the spikes, flashes, and respawns at the last checkpoint" costs about as much as "the player takes damage", and gets you three times as far.

Know when to stop prompting. A small taste call, like where one tree stands, is cheaper as a drag in the editor than as a paragraph. And get the level standing before you get it moving: it is easier to describe what should happen when the thing it happens to already exists.

And play often. Most wasted requests come from asking for the next four things before checking whether the last one felt right.

When you look at other free options, the questions worth asking are what happens to your project if you stop paying, whether there is a watermark or a splash screen, whether exporting costs money, and whether the free tier is a trial with an end date.

Here the answers are: the project is on your disk and stays there, no watermark, no export fee, and nothing expires. The AI is free hosted AI each day, or your own. Flockbay is free.

That is not a trial. The engine is open source and costs nothing to give you. The hosted AI is free each day, and it comes back the next day. You can also build on your own Claude or ChatGPT, and a free ChatGPT account works; any bill there is between you and them, never ours.
