The biggest bill I've gotten from Bunny was like $10 when my app (https://atlasof.space) briefly went viral and got 100k+ views in a month. Bunny CDN is so reasonably priced and the realistic visitor ceiling for my projects is low enough that it's still negligible. The free->paid cliff is typically a lot steeper than this in my experience.

reply> Minimum Account Balance
> In order to keep your service online, you are required to keep a positive account credit balance. If your account balance drops low, our system will automatically send multiple warning emails. If despite that, you still fail to recharge your account, the system will automatically suspend your account and all your pull zones. Any data in your storage zones will also be deleted after a few days without a backup. Therefore, always make sure to keep your account in good standing.
You proactively replenish your balance, so in the worst case, you can just let the account go.
