The idle planet creation game that sits anywhere on your desktop. Watch the birth of a planet, upgrade the Catalyst, discover new biomes, and shape your own solar system while you work or relax.
Terrafactory: Idle Planet
SteamHumanity 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.

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.

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.

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.
