Tiny World Builder

Tiny World Builder is a tiny world simulator that literally lets you click and build entire universes in your browser. We're talking 8x8 grids running at 60 frames per second complete with Crowd AI that wanders around your creation, time-of-day cycles, seasons, weather systems that actually affect the environment—rain creates splashes and puddles, snow accumulates. You've got top-down bird's eye, isometric angles, first-person walk mode where you WASD through what you built. It runs in the browser, it's real-time, and it's got an actual API with OAuth tokens and webhooks so developers can integrate external apps or automate world events. This isn't some toy—it has layer properties, custom asset support, and JSON-webhook integrations for place/erase/save actions. You can generate worlds from prompts, share URLs, collaborate in real-time. There's ambient audio layering for water, wind, and engine sounds.

Look, everyone's building AI chat wrappers. Tiny World Builder said "nah, let's let people actually build worlds" and shipped something that feels like a love child between SimCity and a coding sandbox. It's got the depth of a game engine wrapped in a browser tab. No installs, no downloads, just open tinyworld.build and start placing tiles. The fact that it has developer APIs means people are already integrating this into other tools. This is the kind of project that gets built by someone who just wanted to exist and got way too excited about making tiny worlds come alive.
