Test and try a discord bot on Fly without credit card

Hello,

first of all, I know about that blog post saying that a credit card is required even for the free version… however, I would just like to try out Fly and see if my small application (a discord bot) works on Fly without risking a charge on my credit card or spending $25 for something that doesn’t work out as expected…
As you can see, I’m not abusing this for any big shady stuff like crypto mining or anything.

Is there a possibility to unlock my account to get past:

Error We need your payment information to continue! Add a credit card or buy credit

Thanks in advance!
