I am currently testing Railway on the free plan but with the hobby trial, deploying my discord bot, its likely that I wouldn't need to utilise the hobby plan at this rate so my plan was to just stay on the free plan ($1 per month) - however i noticed somewhere it said when i run out of credits, the deployments shut down, is that in relation to the hobby plan trial or is there no such thing at the $1 per month plan? Or is it a case of when the trial runs out, i am on the $1 a month plan? i can't seem to find a way to add card details without paying for Hobby. If hobby is the only option, i am happy to do so but just confused.
