Most cloud providers have hourly billing (if not smaller). So you can spin up some instances of what you want to try and will only be billed a small amount.

For Google Cloud, a compute engine f1-micro instance is only $4.09/month. Standing it up for only 24 hours is $0.19.

As well, both Amazon and Google have budgets you can set on your account that can notify you if you go over some thresholds you setup. This can help prevent you from spending too much money.
