+1 on banana.dev, I used it for a side project and deployed some custom code and it was a good experience! I liked the pricing model (lack of minimums and pay for usage instead of a "plan") and how you can package up whatever code you want.
Small note here: our billing is changing within the next month, to up-front payments that apply as a credit balance to your account. It still won't have minimums and you'll have the option to set up auto-refill on your balance, so it will functionally remain pay-as-you-go, but just wanted to add flavor to your comment on the pricing model.
Thanks for using us btw, you rock
I pay my cell bill a year in advance - then I never have to worry about a bill ever.
