A real cart, without pretending to be everything.
VibeCart now has durable multi-item cart state and released UCP cart operations. It still does not pretend to provide complete inventory, tax, shipping-rate, returns, or fulfillment systems that are not built yet.
Merchants keep their own Stripe account and VibeCart takes no percentage of merchant sales. Stripe fees and the merchant's Stripe terms still apply.
