An AI game maker with no sign up: Flockbay builds on a guest account

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

You can download Flockbay, open it, and build with its AI without signing up. On first launch the app gets a guest account from our server, with no browser, no email address and no password, and your first message runs on it.

What it does ask for is a download. Flockbay is a desktop app for Windows, not a page in a browser tab, and it is better to know that before you start than after.

What you do not need is a credit card. Flockbay does not ask for one.

Because building runs partly on our infrastructure. Flockbay writes your code on the free Demo or on your own AI, and what it builds with, the library of ready-made objects and the world data, comes from our servers, which serve an account. A guest account is how the app has one without asking you for anything: it belongs to the install, not to an email address.

The tools that genuinely need no account are the ones where nothing runs on anyone's server. That is a real category and it is a legitimate thing to prefer. It is simply a different category from this one.

The usual version of this is account creation appearing the moment anything interesting happens. Here it appears when you share: a play link, a Community profile and the Steam page ask you to save the account, which is a free sign-in, and building never does.

More on this: You do not sign in to use Flockbay. A new install builds on a guest account.

You get the whole builder, and the builder has two sides. Making a project asks which one before it creates anything — 2D or 3D, with the answer read from your description of the game and yours to change — and neither is held back. On the 3D side that is landscape, water, weather, time of day, cameras and NPC behaviour. In a flat project it is ground you drag into place, sprites positioned by hand, and the camera framed by dragging boxes on the running game. Add your own textures, sounds, props and rigs, play, playtesting and exporting. Flockbay is free on your own AI: your Claude or ChatGPT plan, your own agent, or an API key.

You get a desktop app for Windows with Godot bundled inside it. Your projects are real Godot projects on your own disk, not files on our server. That is worth noting given the question: your work is local even though your account is not.

The game you build runs locally on the bundled Godot. Playing it needs no connection and no sign-in, because it is just a game running on your computer.

You build the world by hand. In a 3D project that is terrain, water, weather, buildings and characters, placed and arranged in the builder; in a 2D one it is ground dragged into place and sprites put where you want them. Flockbay writes the GDScript for whatever behaviour you describe, inside your project, and works the same in either world.

You never open a script unless you want to. You play the result and say whether it is right, and that back-and-forth is the normal way of working rather than a sign something went wrong.

A guest account is still an account, and building still talks to our servers. If that is the dealbreaker, it genuinely is, and you should look at tools that run entirely on your machine. Godot itself is free, open source and needs no account whatsoever. It also expects you to write the code, which is the trade.

That is the actual choice on the table, and it is better to make it knowingly than to install three things and be annoyed by all of them.

No email address to build. No card. No connection to any other account for the app to function. Your projects sit on your own disk as Godot projects rather than being uploaded to us.

The guest account exists to attach free usage and generation to an install, which is the only part of this that runs on someone else's hardware. Saving it attaches what you share to a person.

That is the whole of it, and it is a smaller ask than most tools in this space make. It is still an ask, which is why this page leads with it rather than ending on it.
