Humanity couldn't solve interstellar travel, so it learned to build planets. The Catalyst, an artificial core, pulses periodically, pulling matter from the void. Cell by cell, a planet takes shape on your desktop.

Watch your worlds come alive

Earn energy from clicks while you work or relax, then invest it into research that evolves the Catalyst and shapes future planets. Discover new biomes, each with unique properties: volcanic cells erupt in bursts of energy. Frozen rocks form over time and crack under the pulse's pressure. Each planet develops its own character.

Chart your solar system

Launch expeditions and seed new worlds through the Incubator, shaping each planet's surface with your own choices. Earlier planets keep producing while you're away, growing your system passively.

Lives on your desktop

Runs in a resizable window that you can place anywhere on your screen. Your planet grows beside your browser, your code editor, your other game; always there, never in the way.
