Turn your ideas into interactive 3D browser games

Describe a world or a game and get a lightweight, stylised 3D experience that runs on the player’s own device: an obstacle course, an exploration, a kart race, a showroom. Then you edit it with a visual editor and in plain words.

Picture of the scene

A real 3D scene, drawn by your device right now: drag to orbit it, and move “Time of day” to relight it and swing the shadows. Written for this page with no game engine. It illustrates the idea; it is not a game produced by the studio.

What you make with it

Six kinds of experience to begin with

The studio is built for what truly works in a browser: small, polished worlds with reliable play, not vast open worlds.

Obstacle courses

Moving platforms, hazards, checkpoints and a timer. Among the quickest kinds to appear and the most fun to test.

Exploration

An island, a village or a cave to wander through and collect what is hidden. The calm is the point.

Simple kart racing

A track, laps and coins on the racing line. Playful driving, not simulation.

Product showrooms

Your product on a stage, with the visitor orbiting it and switching its colour. Upload your model or start from a simple shape.

Room and warehouse walkthroughs

You walk the place in first person. For introducing a space or explaining a layout.

Puzzle adventures

Floor plates, crates and a gate that opens when solved. Puzzles solved by moving around.

1Describe

From a sentence to a world you can walk through

Write what you want: the kind of experience, what the world contains, what the player is trying to do. Fanann builds the world from simple, colourful shapes, puts a player and rules into it, and shows it in a 3D viewport you can turn yourself.

  • It starts from a proven template for the kind you described
  • A clear switch between “Edit world” and “Play game”
  • A real loading bar, and quality that suits your device
2Light

Lighting and time of day change everything

The same world looks entirely different in the morning, at sunset and at night, as you tried in the scene at the top of this page. In the studio you pick a ready environment, move the sun, set the sky and the fog, and see the result at once.

  • Ready environments and a time of day you can move
  • Sun, sky and fog
  • An instant change, with no AI involved
3Edit

Say what you want and the world changes

For changes that touch many objects at once, you write a sentence: “make it sunset”, “add three obstacles”, “add a timer and a finish line”. For precise changes you open the editor and move the object by hand.

  • Edits in words for broad changes
  • A visual editor for precise ones
  • Saved versions to return to

The steps

How to make a 3D game with AI in Fanann

Five steps, and the third is the most fun.

  1. 1

    Describe the world

    Open 3D Game Design and write the kind of experience and what is in it, or choose one of the seven templates.

  2. 2

    Walk around it

    The world appears in a 3D viewport. Press “Play game” and try the movement and the objective.

  3. 3

    Edit the world

    Switch to “Edit world”: select an object and move, rotate and scale it, add shapes or your own models, and change the lighting.

  4. 4

    Set the player and the rules

    Choose how the player moves (third person, first person, vehicle, orbit) and the goal, the timer and the lives.

  5. 5

    Publish to a link

    Check the performance counter and the world-size meters, then publish. Whoever opens the link plays in their browser.

Honest boundaries

What it is, and what it is not

We say it before you start, not after you have built.

Not console-quality graphicsThe worlds are stylised and light on purpose. No photorealism and no vast open worlds.
No multiplayer yetEach player is in their own world. Shared online play is not available at present.
Performance depends on the deviceThe world is drawn on the player’s device. Quality steps down automatically on slower devices, and some will not run it smoothly.
Browser, not app storeThe experience runs in the browser. We do not produce an app for the app stores.
FAQ

Questions people ask

Is the scene at the top really 3D, or is it a video?
It is really 3D: your device draws it moment by moment, which is why you can orbit it and relight it. If your browser does not support 3D graphics, or you prefer reduced motion, you see a picture of the same scene instead, and changing the time of day repaints it.
Do I need experience with 3D software?
No. You describe the world in words and move objects in the editor the way you move things on a table. The ideas you need are few: an object, a position, a colour, a role.
Can I use my own 3D models?
Yes. You upload them in GLB format within your plan’s size limits and place them in the world like any other object. You are responsible for the rights to what you upload.
Why “stylised and lightweight” rather than realistic worlds?
Because the world runs on the player’s device, which may be a mid-range phone. A polished, stylised world that runs smoothly for most people beats a realistic one that stutters for most of them.
Does it support multiplayer?
Not yet. Today’s experiences are single-player.
Is 3D Game Design on the free plan?
3D Game Design is part of the paid plans as things are set today. The pricing page shows what currently applies and what each plan allows.
When should I choose 2D instead of 3D?
When the idea is about rhythm, precision and quick rounds, or when your audience is on phones of mixed ability. The “2D vs 3D” guide helps you settle it with five questions.
