Shape worlds. Wield powers. Watch civilizations rise.
A free browser-based god sandbox. Sculpt terrain, spawn life, found kingdoms, unleash disasters — every world reproducible from a seed. No install. No plugins. No ads.
Every system written from scratch — procedural terrain, autonomous creatures, AI kingdoms, and disasters that actually compound.
Eight biomes carved from layered noise: ocean, beach, grass, forest, mountain, snow, desert, swamp. Reproducible from any seed.
Villagers, warriors, wolves, sheep, zombies, and dragons run their own state machines. Predators hunt. Prey flees. Dragons hunt anything.
Humans, Elves, Dwarves, Orcs. They grow on food, build houses, tech up across four ages, and expand their borders. War is inevitable.
Lightning ignites forests. Meteors leave craters. Volcanoes emit lava forever. Tornadoes scatter terrain. Plague spreads. Acid rain corrodes.
Bless and curse individuals, shield regions, warp time. The Time Warp button cycles speeds from Pause to 10× without leaving the canvas.
Optional account unlocks unlimited cloud saves, global leaderboards, and 8-character share codes for read-only public worlds.
GodSim is a love letter to the WorldBox lineage — but every line of code, every sprite, every system is original. The simulation runs entirely in your browser on a hand-rolled HTML5 Canvas engine. A lean FastAPI service handles accounts, cloud saves, and the global leaderboard.
No analytics. No external assets. No tracking pixels. Anonymous play works out of the box; signing in only enables cloud saves and the leaderboard.
