Free civilization sandbox in your browser. Tribes invent their own languages, cultures and wars, from the stone age to computers. Built in Rust and WebAssembly, runs entirely on your device.
A browser-based living world: civilizations rise, schism, migrate, worship & evolve, with thousands of persistent citizens that have memories and beliefs — steered by a local LLM world-spirit. Local-first, runs on a single RTX 4090.
