Tiny World Builder - Click and build tiny worlds

Tiny Worlds Builder is a relaxing and fun place to create small worlds of 8x8, 12x12 or larger "boards" all made up of tiles that can contain buildings, trees, farmland, plants and more. Drop a building, then tap it again to change it or drop another next to it and the builds change and adapt automatically. Pan and zoom to see more generative views OR tell AI what kind of world you would like. Once built, play, explore, enter it with VR, display it on a desk in AR or just share it

I built Tiny World Builder as a bit of fun to experiment with generative worlds and easy to use interfaces, and it went viral and grew a big following inspiring people to do the same kind of isometric, 3D creations!

Tiny World Builder lets users generate worlds from prompts, but the API key lives in the browser and the prompt targets a set of primitives (terrain, paths, fences, crops, building clusters, etc.). In practice, how do you structure the generation so results stay editable and consistent—especially compared to image-only “AI world” generators that don’t preserve structure?

@curiouskitty There's some generative non-AI code in there to do world generation based on preferences the user can set, and seeds are used to maintain consistency so that the user can reproduce the world or share that seed to create the same base world.

The changes they make are then saved on top of that and I'm adding the ability to share with a gallery of builds.

This is very much a build in public project so continual development daily!

Selective editing is coming, so add a turret to a mansion and change it's colors and rotate and reposition the doors etc.
