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

The app costs nothing to download, on both Windows, and nothing to use on your own AI. The engine underneath is Godot, which is open source and free in the stronger sense of the word.

On Free, the AI is your own. Flockbay writes your gameplay logic on your own AI: your Claude or ChatGPT plan, your own agent, or an API key. Flockbay builds from a library of ready-made objects, or with Godot's own shapes. What that AI costs is between you and the company that runs it.

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 no team or per-seat tier.

More on this: Flockbay is free on your own AI: you pay the company that runs your model, and Flockbay nothing.

Every time Flockbay writes code, a model runs and 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.

The useful thing to know is that the AI is not the whole product. The builder is where most of your hours go and none of those hours use an AI. Shaping terrain, drawing a lake, setting the weather and placing three hundred objects is you working, not tokens burning — and so is dragging a flat game's ground across a thousand cells, framing the camera, and arranging every sprite that stands on it.

So your own AI goes further here than in a tool where every action is a prompt. If you are careful about what you ask for and generous with what you build yourself, it costs you little, and Flockbay itself costs nothing.

A desktop app for Windows 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 split: you build the world by hand in the builder, Flockbay writes the GDScript, you play the result and say whether it is right. The building half needs no AI; the Flockbay half runs on your own.

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.

Build first and ask second. Get the level standing, then 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 your own, or a plan runs it for you.

That is not generosity, it is just where the cost actually is. The engine is open source and costs nothing to give you. Running a model does cost something, so Flockbay runs on the one you already pay for.
