ONI calculators, planners and mods
Plan an Oxygen Not Included colony before you build, starting from the question in front of it, whether that is air, food, power, heat, ranching, geysers, rockets, morale or research. An Electrolyzer makes 0.888 kg of oxygen per second against 0.1 kg each Duplicant breathes, and ordinary Wire carries 1,000 W; the planners add such values up for your whole plan. The mod directory finds Workshop and Nexus mods by what they change and the DLC they need.
