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.
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.
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.
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
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
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
Ready worlds to start from
Seven templates, each a complete world you can move around in. Here are three of them.
How to make a 3D game with AI in Fanann
Five steps, and the third is the most fun.
- 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
Walk around it
The world appears in a 3D viewport. Press “Play game” and try the movement and the objective.
- 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
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
Publish to a link
Check the performance counter and the world-size meters, then publish. Whoever opens the link plays in their browser.
What it is, and what it is not
We say it before you start, not after you have built.
