This seems like a nice piece of software, and I want to use it, but I have to ask in this day and age. What's your plan here? How do you make money? There is no free lunch these days, and this costs money to keep online too.
Actually my goal is to reach ~1000 users first, and for them it will be free forever or huge free credits because they helped me achieve that goal, and until then yes it will remain free, I will sponsor it at my own costs.
