I like it, it was released a couple of days ago so something might require a bit more polishing but overall it looks better to me.

I have heard of several cloud screw-ups as well, leading to charges of several thousands.

On one side this can happen if you experiment something outside of the free machine(s), on the other side you have all the reporting and notification tools to avoid surprises.

Nonetheless, I still see your point, reason why I prefer to use an almost dry revolut prepaid for all the cloud accounts instead of my main credit card.

As you wish, indeed the only free offer without credit cards is the one of azure for students. In any case you are not anonymous.

Considering the small audience and purpose, I would not have any problem using the always free offerings of either Oracle or Google (the latter especially if located in the US).
