Galaxy Generator
Generate a small seeded galaxy and inspect the stars, planets, and uncertainty behind it. It shows possibilities; it is not a catalogue.
Cosmos
One seeded path from a small galaxy to a stellar system and a selected world.
System Generator
Turn a seed into one star system, then watch the planets, moons, and belts move.
World Generator
Pick a planet or moon and inspect its surface, sky, host body, and detection notes.
All three tools run locally in the browser. Generated classifications are models, not observations.
Local development
Shared engine rebuild: deterministic generation, dynamics, coordinate frames, lighting, schemas, and system history are being separated from the page interfaces. All eight local Node tests pass as of 17 July 2026.
SOL experiment: a separate Rust/WASM Solar System instrument starts from a pinned JPL Horizons/DE441 snapshot. All six native Rust tests pass. It is not connected to these generators or the site background.
