Starter starts with a 30-day free trial; Growth and Business are billed immediately at signup, with no trial. A payment method is required for every plan. On Starter, you will not be charged during the trial — your card is only charged automatically once the trial ends, unless you cancel first. Your card details are collected and sent directly to Stripe from your browser; JsonFabrica never sees or stores your card number.

30 days free, then your card is charged automatically.

Only Starter has a free trial. A valid card is required now, but you won’t be charged during the 30-day trial. If you don’t cancel first, your card on file is automatically charged Starter’s monthly rate when the trial ends on day 31.
