Planetary Industry (PI) lets you set up colonies on planets to extract raw materials and manufacture them into trade goods. It's one of the most reliable sources of passive ISK in EVE -- once your colonies are running, they produce around the clock whether you're online or not.
A single character with Command Center Upgrades IV can run 5 planets, typically earning 50-200M ISK/week depending on the system and products. With multiple characters, PI scales linearly.
This optimizer finds the most profitable colony layouts for your system. Enter your system name and number of characters below, and it will calculate the best products to build using real-time Jita prices, then generate importable templates you can paste directly into EVE.
