A free 3D game maker, and what free usually hides in 3D

What a free AI game maker gives you is defined on that page.

The first is the export gate. The editor is free, and building a finished, distributable game is the paid feature. You find this out after a month of work.

The second is the watermark. Free tier games carry a logo, so free is really a trial with an indefinite length.

The third is the asset economy. The tool is free and every model, texture and sound you might use costs money in a store you can only shop in from inside the tool. In 3D this is the expensive one, because 3D games need far more content than 2D games do.

The fourth is credits. You get a number of AI generations a month and the number is set so that a real project runs out. Free stops being free somewhere around your second week.

Flockbay is free to download for Windows and Linux, and so is the AI. There is no export gate, no watermark, and no reduced engine. The engine is Godot, which is open source and free regardless of us.

Flockbay is free, AI included: free hosted AI every day, or your Claude or ChatGPT plan, your own agent, or an API key. Inference runs over the network and genuinely costs money every time, which is why the hosted AI is a daily allowance that comes back the next day rather than an open tap, and why your own Claude, ChatGPT or key is one press away. Nobody gives away compute without limit, and anybody claiming to is funding it from somewhere you cannot see.

So: the app, the engine and the world tools are free with no asterisk, and the AI is Demo each day or your own Claude or ChatGPT. Nothing you have already made stops working if you stop paying for your AI.

A desktop app with Godot bundled, running 3D properly: terrain, water, weather, lighting, and a game that runs locally on your own machine at your own framerate. That last part is not a small thing. Free browser-based 3D tools exist and they are running your world inside a tab, which is why their example scenes are always small and flat.

You also get a real Godot project. If you stop using Flockbay entirely, the project is still a Godot project. That is a different kind of free than "free while you stay".

More on this: Where assets come from in Flockbay

You describe the game. Flockbay asks what it needs to know, one round at a time with a recommendation for each, and writes a brief: what gets built first, what comes after, what is not in this version. Nothing is built until you approve it. Then it builds the world with its world tools, as real nodes in the scene tree: terrain sculpted and painted, a lake, sky and weather, buildings, characters.

It writes the code too. You say what should happen and it writes GDScript inside your project, then plays its own build before you do: it runs the game, sends input events, reads stdout and the debugger, and captures the viewport. You do not read the code unless you want to; you play the game and say whether it is right. Being non-technical means not writing code, not having no opinion.

When a call is pure taste, like exactly where the shoreline bends, the same world tools are buttons around the Godot editor's 3D view, acting on the live scene with Godot's undo. A sentence gets you a lake; your hand can get you the exact lake. That part is optional.

Building needs an internet connection because the chat, asset generation and world data come over the network. Playing what you built does not.

A 3D game needs far more content than a 2D one and that is where budgets actually go. Flockbay builds from a library of ready-made objects or with Godot's own shapes, and it generates pictures and sound. Generated 3D models run only on your own Tripo key. The other honest source is art you find or buy elsewhere and bring in as your own files.

Built geometry is underrated. A stylised world made of simple Godot shapes, placed with intent, can look deliberate and cohesive in a way that a pile of mismatched downloaded models never does, and it is free in every sense.

Terrain, water, weather and sky are part of the world rather than assets you have to source, so a large outdoor scene starts from something rather than from nothing.
