Station Calculator?

[Fiscal Responsibility]

I've been using http://www.x4-game.com/#/station-calculator
IDK where this is hosted but it's down half the time I'm trying to use it and now I can't complete my complex. What station planners and calculators do you guys use?

X4_ComplexCalculator, it can also handle mods. Though it will crash on the bottom most import option. It can export files that that website can use too, and import them as well.
