You need to dedicate the instance for a full 24 hours, so if you're doing daily builds you'll probably end up paying for a mac mini every month.
Not that I'd ever do or recommend it in a commercial setting, but hobbyists should probably just fire up something like https://github.com/kholia/OSX-KVM to do builds.
Meh, I don't think that too many things that AWS is releasing are at all relevant for hobbyist because of pricing. I
n this case, you need to pay at least 16 usd for running this because of 24h limitation, so for example using scaleway (2.4EUR for 24h) or just buying a mac mini probably is gonna be cheaper overall
